In 1968 a man had the idea to create the first tablet in history. The problem is that he was decades ahead of his time.

If I tell you to think of the oldest tablet you remember, you may go back to the first iPad, which was released in 2010 (and, by the way, I turned seven last week). Or, if you’ve been following the world of technology since before the turn of the century, you might be familiar with the Microsoft Tablet PC from HP Compaq that was announced in 2001. In reality, there was someone who already tried to create one and it was much earlier, in 1968before the term “tablet” was even coined. At that time, Alan Kay was a young worker at the Xerox Palo Alto Research Center who had been mulling over the concept of a personal computer for some time (in contrast to the military, business and professional use that reigned among manufacturers at the time). After speaking with other colleagues who were beginning their research on how the programming language Logo could help younger children advance in math, Kay came up with an idea: “This encounter finally made me see what the real destiny of personal computing was going to be. Not a personal dynamic ‘vehicle’, as Englebart’s metaphors had it as opposed to IBM’s ‘railway tracks’, but something much deeper: a dynamic personal ‘medium’. With a vehicle, one could wait until high school to take ‘driving lessons’. But if it was a medium, it had to extend into the world of childhood.” In 1968, Kay created the Dynabook conceptwhich he would spend several years profiling. in the book “Tracing the Dynabook: a study of technocultural transformations” They define it like this: “Kay called it the Dynabook, and the name suggests what it was going to be: a dynamic book. That is, a medium like a book, but one that was interactive and controlled by the reader. It would provide cognitive scaffolding in the same way that books and print media had done in recent centuries but, as Papert’s work with children and Logo had begun to demonstrate, it would take the advantages of the new computing medium and provide the means for new kinds of exploration and expression.” “A personal computer for children of all ages” With the idea of ​​its function clear, Kay then began to shape it into cardboard prototypes (as can be seen in the image at the top of the article). In 1972, the researcher presented his paper “A personal computer for children of all ages” in which he offered more details not only about his motivation and his vision of personal computing at the time, but about the own device that I had in mind. His idea was to get a kind of tablet-shaped personal computer aimed at education. This would have a reduced thickness, a liquid crystal touch screen and a keyboard. Like a regular notebook in size, with a graphical interface (a revolution for the time) that allowed the reproduction of graphics, music and text, and with internal storage for 500 pages. The keyboard would not be the only way to enter information: it could also be done via voice. In the image that Kay drew, the word “stylus” can also be seen, although he did not comment on it in his paper. Kay’s idea is that the Dynabook that could be connect to other systems to “copy” information to it (among them, the ARPA Network) and even predicted the existence of content “vending machines”, which could not be accessed until payment had been made. “The books can be installed instead of being bought or loaned,” he said. Regarding digital “ownership”, Kay said the following: “The ability to easily make copies and own the information yourself is not likely to weaken existing markets, as has happened with xerography, which has strengthened publishing; and just as tapes have not hurt the music industry but have provided a way to organize one’s own music. Most people are not interested in being a source or a smuggler, but rather like to trade and play with what they have.” According to Kay’s calculations, the components to manufacture it could cost $294, so it was not unreasonable to be able to sell it for $500, something expensive for the time. “The average annual amount spent per child on education is only $850,” he said, and that is why he even proposed a different financing model: “perhaps the device should be given away as if it were a notebook, and only sell the content (cassettes, files, etc.). “This would be quite similar to the way TV packages or music are now distributed.” “Let’s do it!” he said to finish his paper. Unfortunately for Kay, the Dynabook never materialized. Despite Kay’s enthusiasm, the Dynabook itself was never manufactured for lack of support at Xerox and due to the technological limitations of the time. Do you remember what computers were like then? Well, imagine what it would be like to build a tablet. Two Xerox PARC engineers, Chuck Thacker and Butler Lampson, asked for permission to try to replicate a similar machine on their own, and so it came to light. Highwhich was also known as “Interim Dynabook”. It was not a tablet, far from it, but it maintained some of the ideas that Kay had raised in her publication. He Xerox Alto was one of the first personal computers of history and Steve Jobs and Apple engineers they were inspired in some of its innovations and concepts, such as the use of a graphical interface for its own computers. Starting at Minute 2:27, the Xerox Alto graphical interface in action Kay is not only remembered for the Dynabook itself, but for the educational vision he gave to the project, for his peculiar vision of the personal computing paradigm and for how he came to anticipate some of the problems (and even technologies) that would come later. Not only that: in 2001, Microsoft presented its Microsoft Tablet PC, a project that Chuck Thacker and Butler Lampson had led. Yes, the same ones who once tried to implement … Read more

found RAM memory modules worth 500 euros in the worst time to buy them

A Reddit user counted this week how he had a singular habit: rummaging through his neighborhood trash can in case he found some hardware treasure. And boy did he find it: among other things, he got two 32 GB DDR4 memory modules. Those modules thrown away as waste are a little treasureespecially because with the memory crisis Its market value exceeds 500 euros. what has happened. The user, who uses the alias “ringosbigfuckingnose” indicated that he makes regular visits to the local landfill in his area to look through the garbage that people throw away in search of components for their old PCs. He pointed out how he often comes across equipment from which he can salvage things, but the other day he found a real treasure: A Samsung monitor A 5.25″ floppy drive A 5-bay Drobo NAS Two 32 GB DDR4 memory modules A 10th generation Core i7 with its fan An ASUS motherboard A real find, without a doubt, but above all for one thing. 64 GB of RAM is 500 euros in your pocket. All of these components have value, of course, but it is especially striking that I found those two memory modules with a total of 64 GB. If you take a look around stores like Amazon or PcComponentes you will quickly see that two 32 GB DDR4 modules have a price that today is difficult to lower than the 500 or almost 600 euros. An absolute treasure. An ingenious solution to the memory crisis. What this user has achieved is to find a unique solution to the RAM memory crisis that has caused prices to rise. they shoot in an absolutely extraordinary way. It’s not likely that many people are throwing away memory modules lightly, but there are certainly plenty of people who find real treasures – especially in the form of old consoles and computers – in garbage dumps and recycling centers. And what for some is trash, for others is a small (or big) gem. On TikTok it’s easy find videos with people finding some devices that may be damaged, but that have possibility of being repaired. Electronic waste that is not waste. The Reddit user commented that he lives in a city of about 8,000 people, and the local landfill has a container for recycling electronic waste, something similar to what happens with the recycling centers or clean points that we find in Spain. It was in that part where this user found all those products as is, available for pickup. electronic waste. As they pointed out in Windows Centralthere are studies that indicate that less than a quarter of electronic waste is recycled properly. That means there is a lot of money wasted in the form of still valid hardware and also minerals and components that can be mined from those components.

AI saves us time but takes away the story

A few days ago I surprised myself doing something that five years ago would have seemed sacrilege. I had in front of me one of those reports that you save to read on Sunday morning. 5,000 words, a prestigious signature and a great design. A text of those who ask for calm. And when I didn’t even have two sentences, I instinctively looked for the ‘summary’ button that now crown my browser. Nine lines. That was the whole summary. It was not for lack of interest, it was rather for that modern urgency that whispers to us that spending twenty minutes on a single idea is an inefficient thing. After a quarter of an hour I remembered almost nothing of those nine lines. I had the information, but I didn’t have the knowledge. We are turning reading into an administrative procedure. What started as a survival tool to deal with the deluge of work emails or some long-winded Reddit threads has colonized our capacity for wonder. In 2026, AI not only helps us write, it also is teaching us not to read. Or even worse: it is convincing us that the path is a hindrance to reaching the destination. It is the definitive victory of the TLDR about curiosity. The problem with outsourcing digestion is that we start from a false premise: that the substance of things is the only thing that matters. But in culture, information or in a simple conversation, substance is sometimes the least important thing. Ask an AI to summarize Don Quixote for you and it will tell you that it’s like a man from La Mancha who has read too much and confuses windmills with giants. You have the information, but you have not heard the conversations with Sancho on the roads. You have not felt the bitterness on the beach in Barcelona nor the lucidity of someone who regains their sanity to realize that the world, without its madness, is a gray place. Technology, in its efforts to eliminate friction (paradoxically, being the one who has blocked our notifications) is taking away the fabric of our experience. Silences and nuances are what fixes memory. The horny thing is What are we using that time for that we supposedly save by not reading?r. It is not to think deeply or to walk around without a cell phone and hit the coconut, but to consume even more summaries. It’s a loop infinity (pun intended) empty efficiency. We optimize the consumption of information to be able to ingest more information, which in turn we summarize in the next scroll. Thus we become archivists of a life that we did not get to witness. We save, synthesize and archive, but we do not inhabit anything. We are reaching a phase in which the true status, the intellectual luxury of our era, is not to be very smart or to be up to date with everything thanks to our AI agent, but in be able to sustain attention. Prestige belongs to those who can afford the extravagance of reading a text from beginning to end, of listening to a podcast without skipping the silences or set it to 1.75x. Or finishing watching a movie without having used your cell phone for two hours. Efficiency is a great metric for an assembly line or an AWS server, but If we let it guide the leisure of a human life, we are making ourselves a little miserable. We start by optimizing each minute to end up leaving everything in a list of three key points. Or in a nine-line summary. But life cannot be summarized.

Companies are replacing junior workers with AI. Now it’s time to pay the consequences

When artificial intelligence appeared on the horizon, the first thing we thought was that it was going to retire us. Later, he was going to retire the most senior profiles and now we know that it is just the opposite: is stopping job access to junior profiles. In the past, companies competed fiercely to attract young talent, but now Gen Z has found its great rival in AI. Beginners? No, thanks. This Revelio Labs job report reveals that entry-level hiring has fallen by 35% in the United States since 2023. And it is one of many studies: this other of job offers estimates the drop in junior offers between 11 and 20% in the last year. The phenomenon is not exclusive to the United States: in Spain these data from El Confidencial They report that the Big Four are going to reduce the hiring of people under 30 years of age by between 10 and 20%. In the UK, more of the same. AI boosts productivity… if you’re the boss. The business premise is that artificial intelligence can carry out these tasks of those people with a junior profile such as documentation, testing or writing basic code. It is not that these tasks have disappeared within the workflow, it is that they have been absorbed by higher levels in a twist of efficiency and productivity: senior profiles supervise what the AI ​​does. And if, AI screws up. To the question of how many hours of work per week does AI save you? from the consulting company Section collection in The Wall Street Journal There is a clear divergence between managers and staff: 40% of workers think that they are not saving anything because even if there is a quick response, there are errors and hallucinations. When you take into account the time spent going through everything, checking and redoing, the beads are not so round anymore: this Asana studio shows that employees spend 4.5 hours per week correcting AI work. The boomerang effect. That youth encounter yet another obstacle to having a full adult life is a real drama in terms of unemployment, but this paradigm shift in hiring is also a total threat to the stability of the technological infrastructure as we know it: The illusion of efficiency. AI chops code faster than anyone else, but that raw data is misleading because it doesn’t consider side effects like validation. Operational risk. If the AI ​​does not have human supervision at each step, it can make critical errors, serve as an example when half the internet went down for the total automation of Amazon servers. Of costs and responsibilities. If the AI ​​makes a mistake and it reaches the final chain of the process, that is, delivery to the customer, it is paid. Let them tell Deloitte, they had to reimburse the cost of a report prepared for the Australian Department of Employment and Industrial Relations because it contained hallucinations. A demographic bomb. All of the above is a toll that many companies seem willing to pay for the sake of that efficiency, but there is a devastating effect on a large scale in the medium and long term: the knowledge gap. When these senior profiles retire, there will be no one who can replace them simply because you have eliminated the training ground that is experience. The figures have spoken: between 2024 and 2032, 18.4 million professionals in the United States will retire according to this study from Georgetown University. However, only 13.8 million new workers will gain access. About to explode. Part of the work of senior profiles includes mentoring and all its intrinsic benefits: there are studies that confirm that increases motivation, promotes psychological well-being and even reduces exhaustion. In short: saturation of tasks, inability to delegate and the loss of that added bonus of teaching: there are many ingredients for the recipe for burnout.

The time it takes to get to a highway anywhere in Spain, on a revealing map

Faced with the pressing housing problem in Spain In large cities, one of the simplest solutions for those who can afford it is to leave stressed centers such as Madrid or Barcelona in search of more accessible municipalities and properties. How much? It depends on your budget, what your work is like and what the destination location offers you in such objective terms as services and infrastructure. And there is one essential to move: the distance to a main road. I speak with knowledge of the facts: this was a key factor when choosing a municipality to buy an apartment months ago. My new location has direct access to the highway and getting from there to my trusted padel club in Pamplona is 10 minutes longer than doing it from my old apartment, located in the center of the Navarrese capital. Although it is not ideal, my pocket has appreciated it and the sacrifice is profitable for me. Now, having chosen an idyllic municipality in the Navarrese Pyrenees would have been a very bad idea in terms of mobility (although bucolic on days like today). That was my personal decision, but given the prices, I know that I am not alone: ​​from buying in the capital to doing so in a municipality in the province there are price variations of up to 131% in Madrid or 126% in Álava, according to the latest Idealista study that collects La Razón. Because if the price of the property in Villagónadas de Abajo is the lowest in the province but it is where Cristo lost his lighter, already such. Well yes: the price differences are abysmal and the communications are too. An x-ray of territorial inequality and Spanish orography This map created by Digital Cartography With data from the Ministry for the Ecological Transition and the Demographic Challenge, this is evident. The cartography collects the minutes by car to a highway or highway from a good part of the Spanish state (if there are no this type of roads, as happens in Ceuta or Melilla for example, then they do not appear) with information from 2022. To see everything in a more intuitive way, they have used the colors of the traffic light, where green is what can cost you up to 20 minutes and red goes from one hour to 133 minutes in the maroon areas. The access time to a highway or highway in Spain. Digital cartography with data from the Ministry If we superimposed a physical map with a demographic one we would find a clear diagnosis of red zones in critical areas such as the Asturian massif and the Pyrenees, the muga with Portugal (especially in Zamora, Salamanca and western Extremadura), the Iberian System and the maximum expression of “Empty Spain” in the south of Teruel, the north of the basin and areas of Guadalajara or the Betic Systems. We know that in communications Spain It is a centralized state with Madrid as the nerve center and the lines of these main roads, although they do not appear on the map, can be intuited. Without going any further, it is not too difficult to imagine where the A-2 goes to Barcelona or the A-6 to A Coruña. That is the first clue as to why we find such an uneven map: the radial network model, which leaves enormous gaps in peripheral areas that are not linked to large state/European corridors. Obviously the extreme orography of the Pyrenees or the Iberian System makes construction difficult on a technical and economic level (it is not that it is not possible to lay out viaducts or tunnels, it is that it makes the cost skyrocket), but the Average Daily Intensity mandates: for a public work to be approved there is a cost-benefit analysis and if an area has a low population density, the ADI is low, making it difficult to justify the investment. On the other hand, there are environmental restrictions: some of these red zones coincide with national parks or protected areas. In this scenario, obtain a Environmental Impact Statement (mandatory in projects of this magnitude) is an impossible mission. The small print. Something that I greatly appreciated when I returned to Navarra is that there is no traffic… compared to Madrid. The rush hour for leaving work or school may be noticeable in a few minutes of delay, but it is light years away from the traffic jams that I have had to suffer in return or bridge operations when I lived in the state capital. Because although in Madrid almost everything is green, in practice those minutes correspond to a distance traveled respecting the limits of the road and assuming fluid traffic.

For the first time, electrified cars are outselling gasoline cars. It is the beginning of the inevitable

We already have the data on car registrations in 2025. And the inevitable has become reality: the electrified car has prevailed. Driven by countries like Germany or the United Kingdom, the alternatives to the combustion car make it clear that the future of the industry depends, yes or yes, on a plug. A discreet recovery. EU registration data for 2025 shows a clear trend: a significant increase in the registration of both electric and hybrid vehicles. Overall registrations rise by a discreet 1.8% but the change is not in the total volume, it is in the type of car that is sold. The data. The pure combustion vehicle is beginning to reduce its share in the European market. HEV (hybrids and microhybrids): 34.5% Gasoline: 26.6% BEV (pure electric): 17.4% PHEV (plug-in hybrids): 17.4% Diesel: 8.9% Others: 3.3% He electric car It already occupies third place in the ranking, doubling sales of diesel cars but below hybrids. Adding figures, the year-on-year variation (YOY) in December 2025 was an increase of 51% for pure electric cars and 36.7% for plug-in hybrids. The key countries. Figures from January to December 2025 show a substantial increase in electric car registrations in countries such as Germany (+43.2%), the Netherlands (+12.6%) and France (+12.5%). The data in countries like Spain is striking, which lead the growth in hybrids (+23.1%) and plug-in hybrids (+111.7%) in the latter case. The decline of combustion. At the end of 2025, gasoline car registrations fell by around 20%, and 24.2% in the case of diesel car registrations. If these figures are sustained in the short term, it will not take long for purely electric vehicles to surpass gasoline vehicles at the European level, placing them in second place in the ranking below HEVs. A bit of a trick. The photograph is clear: the electrified vehicle is growing at a rapid pace, but in cases like Spain there is some fine print. We are the country that has grown the most in adoption of HEVs (hybrid vehicles), but this category also includes MHEV. These are vehicles that combine a combustion engine with a small electrical system (generally 48V) and a low-capacity battery. They never circulate in 100% electric mode, but the small electrical system helps reduce emissions and consumption. Yes, but. It is also worth remembering that the total number of registrations does not only tell us about the preferences of individual users: the data reflects the registrations intended for companies and renters. Specifically, passenger car registrations in 2025 were quite distributed, with 50,213 in the case of channels for individuals and 43,362 for companies. The Transportation electrification is moving companies to buy electrified vehicles in volume, to comply with future European restrictionswho have recently lowered their forecast of reducing carbon emissions by 100% to now talk about 90%.

There is a perfect time of year to ask for a raise: January to March

The first quarter of the year is strategic for companies since in those months the annual salary reviews are closed, taking advantage of the fact that the real results of the previous year are known and decisions are made. concrete adjustments in budgets for that year. For this reason, this first quarter offers a window of opportunity for negotiate salary increases because companies know exactly what budget they can allocate to these salary increases. Doing so during this period makes it more likely get a raise than in July or October, when that budget is already allocated. Increase season: January to March. The natural cycle of many organizations places January as the start of salary reviews, just after closing last year’s accounts, and those for the new year are being planned. As and as you remember Andrea Ramos, the expert in Human Resources and recruitment, in one of her latest videos, during that first quarter, those responsible for human resources and management have a fresh and precise vision of the margin available for increases, which means that your request arrives at a time when adjustments are already being distributed based on real data. A meeting at 11 in the morning. Attempting a negotiation outside this time range, such as in spring or autumn, is usually counterproductive because it does not fit into the company’s internal agenda and may be perceived as out of date. In fact, studies analyzed by the Oberta University of Catalonia not only recommend that the salary review be done in January, but they even refine by proposing a time to request it: 11 in the morning. According to María Naqui, collaborating professor of the Psychology and Educational Sciences Studies at the UOC, “11 in the morning is a good option because having high cortisol levels drives us to make decisions. Even so, asking for a salary increase is something personal and not all of us function in the same way.” That is, not only would you be in the appropriate window of opportunity to obtain the salary increase, but the person responsible for giving it to you will have a greater predisposition to do so. Everything adds up to put things in your favor when you have already decided overcome fear to ask for a salary increase. You have to prepare the meeting. In his video, Ramos highlights that before any talk about salaries it is necessary to add a context that reinforces that request. “Write down a list of measurable achievements from the last year,” the expert recommends. This step provides a base of objective evidence to not depend only on subjective perceptions, but on facts that anyone can verify in internal reports. Next, compare your official job description with the tasks what you really do in your daily life and value that difference between the tasks and their initial assignment and the impact on the company of what you are really doing. However, the most important point is investigate the salary band market for your exact position. That is to say, How much are other companies paying? in positions similar to yours. This will allow you to establish a new realistic range and enter the conversation with verifiable data in hand of your target salary and the minimum you would accept. Open petition. Something that Ramos especially highlights in his video is that, after present with objective data arguments that justify the salary increase, the approach to the issue should not be done with a formula that leaves the door open to a yes or no, but rather forces the personnel manager to offer a reasoning. “What would have to happen for that salary to be reviewed in the coming months,” suggested the hiring expert. With this open formula, the promotion is not considered as an immediate decision, but as the result of a process, forcing the person in charge to establish an assessment of your current position, conditioning it on goals and objectives. Not just to make a closed election. If you don’t get the raise immediately, you have already gotten the necessary steps on the table to get it later.

They already add 30,000 in just three months and at a time of record profits

Amazon has confirmed the layoff of 16,000 workers worldwide, just three months after announcing the elimination of 14,000 positions. The company communicate the cuts as part of a plan to “eliminate bureaucracy” and streamline its organizational structure. The interesting thing is that the announcement comes at a time of record profits. Why it is important. This is the second large wave of layoffs at Amazon in just one quarter, bringing the positions eliminated to around 30,000. The figure becomes more relevant if we consider that next week Amazon will present its financial report, where Wall Street analysts expect revenues of more than $211 billion and profits of more than $21 billion, according to inform The New York Times. Cuts especially in the United States. The layoffs primarily affect Amazon corporate employees, who make up about 350,000 of the company’s 1.5 million total global workers. According to account BBC, most of the cuts will be concentrated in the United States, although some positions in the United Kingdom could also be affected. In the October wave, more than 1,500 positions were eliminated in California alone, most of them software engineers. How to the workers have found out. He official announcement It has arrived after an error. According to explains BBC, On Tuesday night, Amazon Web Services (AWS) workers received a calendar invite to a meeting the next day. A draft message signed by Colleen Aubrey, senior vice president of applied AI solutions at AWS, mistakenly appeared in that invitation, detailing the layoffs under the codename “Project Dawn” (Dawn is the name Amazon uses internally to refer to the layoffs). The message was quickly deleted, but the media had already covered it. It was hours later when Amazon published the official statement. Restructuring. Beth Galetti, senior vice president of people experience and technology at Amazon, wrote in the official post that the changes seek to “strengthen the organization by reducing layers, increasing ownership and eliminating bureaucracy.” He added that they do not plan to establish “a new pace” of reductions every few months, although he left the door open, adding that each team will continue to evaluate its structure “as appropriate,” especially “in a world that changes faster than ever.” Where the money goes. As Amazon cuts tens of thousands of corporate jobs, it is investing massive amounts in another direction: artificial intelligence. According to the NYTthe company spent $125 billion on new data centers and other capital investments last year, primarily to compete in the AI ​​race. Amazon CEO Andy Jassy already warned last summer to corporate employees that artificial intelligence would mean that, over time, the company would operate with fewer such workers. Contradictions. In autumn, Jassy told investors that the layoffs had less to do with AI or finance and more to do with reducing bureaucratic layers. However, according to point NYT, reductions in several divisions were based on specific goals to cut operating costs. All this while in the quarter from July to September, sales reached 180,000 million dollars and profits exceeded 21,000 million. Yocollateral impact. On the other hand, just before Amazon’s announcement, UPS also has communicated which plans to eliminate up to 30,000 jobs this year. Guardian share that UPS has been working to reduce the millions of low-value deliveries it makes for Amazon, since although it is its main customer, this large volume of shipments provides “little benefit”, referring to the fact that they are cheap packages that represent a high operating cost for the company. What happens to those affected? Just like share company, laid-off employees in the United States will have 90 days to look for an internal position at Amazon before permanently leaving the company, although the period varies by country. Those who do not find or seek a new position will receive compensation, outplacement services, and health insurance benefits.

The big problem with lithium ion batteries is their degradation over time. A chemical adjustment can change it

It doesn’t matter if it’s a mobile phone, a laptop, the Nintendo Switch or a Dyson: as you use it, the battery life will reduce. Yes, lithium ion batteries they have changed the world and for years they have been the absolute standard in consumer electronics, but degradation over time is their endemic evil. While we look for alternatives To this technology, a research team has found a promising solution in a seemingly simple chemical tweak. The advance. The main idea of ​​this research is not to change the main materials of the battery, but simply to add a small amount of an additive: lithium difluorophosphate. Its existence is not new, but this research led by Professor Chunsheng Wang of the University of Maryland reveals how effective it is in stabilizing batteries. Why is it important. Because lithium ion batteries are present everywhere and this modification would extend their useful life using standard, low-cost chemistry. The result of their experiment is that with this additive, batteries can be optimized to maximize power and energy, or to achieve greater useful life and stability. For practical purposes, the study shows how with this adjustment they maintained a significantly higher capacity after hundreds of charge and discharge cycles. As Wang explains.“It is a relatively simple modification of current batteries.” Or what is the same, after having run security tests and long cycles, “it could realistically reach consumers.” Brief notes on the mechanism of a battery. Lithium ion batteries are made up of a negative anode and a positive cathode and have a porous separator between the two. The assembly is immersed in an electrolyte whose mission is to allow lithium ions to move between electrodes during charging and discharging. With the discharge, the anode releases electrons to the electrical circuit (gives electricity to the device) and ions to the electrolyte, meeting again at the cathode. Upon charging, an external source (the charger) reverses the process by “pumping” the ions back to the anode to store the energy in the chemical structure. The degradation of its capacity with use occurs due to the irreversible loss of lithium in secondary chemical reactions and due to mechanical fatigue of the electrodes.

If we delve a little deeper into the previous explanation, the solid electrolyte interface (SEI) appears, a thin layer that forms on the anode during the first charges. In standard batteries, this layer is fragile and breaks down with use, consuming lithium and reducing battery life. Through a simple reaction inspired by organic chemistry, this additive makes the electrolyte more prone to accepting electrons, making degradation more controlled. In short, it helps to form a more robust, elastic and uniform SEI, thus acting as a kind of shield that prevents the electrolyte from reacting parasitically with the electrodes. In addition, it is a flexible chemistry that can be adjusted to be more or less protective and the presence of the additive minimizes the presence of cracks in the cathode.
