In the center of Africa a race for minerals that moves the world is fought. And China is winning it

by

Lithium, cobalt, nickel, copper and, above all, Rare earth. These are some of the minerals and metals that dominate the world today because they are key to current and future industries. Revolutions such as renewable energies or that of the electric cars They go hand in hand with these materials, but they are also key to medical, aerospace and military industries. China It has advantage because Master the extraction and processing of key raw materials, but also for its enormous influence on the great world mine: Africa. Treasury search. We are talking about a key territory not only as a business opportunity, but as fountain of critical strategic minerals for the development of technologies that move the world and, also, the future of industries such as that of renewable energies or the electric cars. This is something that has encouraged several countries to want to invest in Africa, since ensuring certain resources is to cement that future. What countries are key? Congo Democratic Republic – It’s about the great world mine when we talk about copper, gold or cobalt. It is estimated that 70% of the world cobalt is extracted only in this country, but it is also crucial for coltan, tungsten, lithium or bauxite. The technology industry cannot work without them. Gabon – Another prominent territory when we talk about gold, but it is also an important source of manganese, iron and other essential minerals. China strategy. China and Western countries are very interested In those two countries in particular, but there are others, such as Zambia, of which they extract more lithium, metals of the platinum or nickel group. But China’s strategy is something that attracts attention throughout this panorama. The Asian giant has been doing years investments Of more than 10,000 million dollars to exploit the mines, extract the materials, process them and send them to China. They control the entire supply chain of these key minerals and esteem that import about 4,000 million dollars in minerals and metals every month. Central Africa is a priority area for China’s supply, but that is also an opportunity for the African countries involved. Investments and opportunity. Within China’s strategy, there is something that is very important: politics. Summits and bilateral agreements are held to ensure access to resources by China, but African countries also remain with their part. Within that interested investment in China, we see that ports, roads and railway lines are being developed. Jobs are also created, joint laboratories and training centers are created to strengthen scientific and technological cooperation. Geopolitics and debt. But, as is usually the case, there is a dark side in this story. On the one hand, competition between China and other global actors. That growing influence of the Asian country in central Africa is not something that makes the United States or European countries. It is something that generates more tension between them, but can also contribute to the tense political and economic stability of the African regions involved. There is studies that point in lack of transparency in contracts and the possible cooperation with authoritarian regimes to extract those resources. And they have also observed some risks of over -indebtedness by African countries. Arms. In all that geopolitical, commercial and collaboration context, and taking into account that we talk about territories with political instability and several armed groups, we cannot overlook another lucrative business for China: the sale of weapons. As we read in South China Morning Posta report by the Rand Corporation prepared in 2023 placed China as the main arms supplier for sub -Saharan Africa. Between 2019 and 2023, at least 21 African countries received great deliveries from Chinese weapons that includes weapons, ammunition, artillery, rockets, drones, missiles, armored and electronic warfare systems. It is also estimated that 70% of African armies use Chinese armored armored extended Its presence in countries such as Senegal, Ivory or Mali coast with new offices. This goes far beyond armament, since China also exports military and private security forces to protect the country’s mining interests. And this occurs because Chinese military exports are usually cheaper and with lower political conditions than Western alternatives, which is very sweet to those African states with a geopolitical context that is not stable. An asymmetric relationship. It must be added that China promised an investment of 50,000 million dollars in three years in the region and that it has pledged to train police and military in the area, but as already pointsall this investment in Africa is generating is an asymmetric relationship between countries. It seems that Africa is receiving much more than China because the former let them exploit their mines and the latter invest in infrastructure, employment, safety and sell manufactured products, but in the end what is achieved is that Chinese influence is huge in Africa. This rapid expansion in recent years causes sovereignty to be questioned and reinforce the idea of ​​what will happen in the area when strategic minerals have been extracted, since many depend on those Chinese investments, seeing how their local economic and political autonomy can stagger. And it must also be said that what we now see with China is something that, traditionally, have carried out other countries in those same territories, and it is something that they are in competing With its great adversary right now: the United States.

A bacon carved in stone

by

The food It is an artbut also a history lesson. Dishes like Torrijasthe lasagna or the sushi They have centuries (and millennia) behind them and tell us a story of use, mix of traditions or even Evasion of pandemics. But although we enjoy food to luxury levels, not so many dishes have become a national treasure. Literally. That is an honor reserved for a few, and the meat -shaped stone of China has the honor of being one of the three treasures that attracts hundreds of visitors every year to the National Museum of the Palacio de Taipei. Your Dongpo. Today, the Dongpo pig is a traditional dish in China, but arose in the province of Hangzhou during the Song dynasty (between 960 and 1279) to take advantage of a curious surplus of pork bacon. Counts the legend that his inventor was Your Dongpoa poet, calligraphy, musician, historian and politician – among other things – who held important positions in the imperial administration, but due to disagreements with a politician, he was banished to Huangzhou. There he became governor and, after organizing a series of actions to dredge a lake and end the floods, was presented with large amounts of pork bacon. The scholar was also a good chef, so he decided to slowly cook the bacon with Shaoxing wine and soy sauce to return the detail to the neighbors (and to take advantage of that surplus with which he had been found). As always, this is a legend and there is Other versions They say that the man was playing a board game, he was clueless and forgot about the pig he had on the fire. When he realized, he discovered that this exaggerated cooking had left the tremendously tender piece. Pig. Such was the acceptance of the dish, which decided to baptize it with the name of the polymata. For almost a thousand years, it has remained one of the traditional dishes of the country and the key is both in the piece and in cooking. About the first, the rule dictates that it must be a bacon bucket of about five centimeters sideways. It must alternate layers of lean meat and fat to prevent it from being too fatty or heavy. And, to achieve this, a slow stroke and a mixture of fermented wine and soy sauce are used. It is a soft, juicy dish that has a characteristic aroma that, as we say, is a symbol of Hangzhou’s gastronomy. Qing dynasty. The centuries passed and the Qing dynasty. China governed between 1644 and 1912 and, it was this last imperial dynasty of the country that raised China in the international scene, making it one of the largest and most prosperous empires in the world in the 18th century. That bonanza period was accompanied by a apogee of the arts that combined innovation and tradition. The Qing acted as patron in many artistic fields, being the sculpture one of the favorites of some of its emperors. And in that period of splendor It arose Something that has become one of the strangest, funny and, in turn, a tribute to China: a tribute to Dongpo pig. Meat -shaped stone. Used jaspe veiled As a main element, the artisan shapes a piece with practically perfect measures of 5.73 x 6.6 x 5.3 centimeters. Not only did he stain the stone to perfectly imitate the appearance of fat and lean flesh, but he was able to create small holes that simulated pork pores. It reflected all layers with precision: from crispy skin, the different interior textures and the base, and all this with colors that really seems marinated meat in soy sauce. One of the three treasures. You just have to see the images that accompany this article to appreciate that artist’s technical excellence. And such is its importance that meat -shaped stone has been described as the most famous masterpiece of National Museum of the Palacio de Taipei. It has been exhibited internationally, attracts crowds and, together with the Jade col and al Mao Gong Dingis the work that reigns In the galleries of the Taiwan Museum (something that should not be very funny to China, precisely because of the constant geopolitical tensions with the country). And here we have a perfect sample of how history, art, tradition and kitchen shake hands thanks, because we must not forget this, to the creativity that artisans could deploy during a qing dynasty that gave wide manga to create sculptures that would delight the court. Unfortunately, as with so many artistic pieces, We do not know The name of the artisan.

Space agencies do not match

by

The failed Soviet ship Kosmos 482, Designed to land in Venushas entered the earth’s atmosphere after 53 years giving tumbos around our planet. However, nobody knows where exactly has fallen. Context. As a twin of the famous Venera 8 capsule, Kosmos 482 was intended for Venus, but was caught in an elliptical orbit around the earth due to a rocket failure that in 1972 promoted it to space. Since then, atmospheric friction has gradually reduced its altitude, which has culminated today in its inevitable fall. Despite The reentry was an expected eventthe different space agencies and follow -up organisms handle varied predictions. According to Russia. The Russian Space Agency Roscosmos He published in Telegram that the Kosmos 482 probe had entered the dense layers of the atmosphere at 06:24 UTC on Saturday. He did it in the Indian Ocean, some 560 kilometers west from the island of Andamán del Medio. Or as some rushed to point out, west of The famous Northern Sentinel Islandthat of isolated indigenous people. According to Europe. For its part, the European Space Agency Space Waste Office Place the reentry between 06:04 UTC and 07:32 UTC. The ESA radars in Germany did not detect the probe after that time, so the reentry is confirmed, although no direct visual observations or ground impacts have been recorded. The central prediction of ESA points at 06:16 UTC, which would place the reentry south of Turkmenistan, on the border with Iran and Agfanistan. According to the United States. The United States space force published through its Space-Track system that the Kosmos 482 reentry had taken place between 05:20 and 05:44 UTC over the Pacific Ocean. This prediction not only It is not consistent With the ESA and Roscosmos reports, but it is invalidated by the detection of the ship over Germany at 06:04 UTC, according to ESA radar data. Where is the capsule. The Dutch Langbroek Satellites tracker It is “reasonably consistent” with its own modelwhich makes a difference of just 15 minutes. That fell into the Indian Ocean, relatively far from any populated area Already daylighthe explains that we have not seen visual material from the reentry. It could be floating. If the capsule survived the reentry, the surface of the Earth hit a speed of about 240 km/h, generating a kinetic energy comparable to that of a meteorite between 40 and 55 cm. The particular thing about this reentry is the robustness of the Kosmos 482 capsule, designed to survive accelerations of up to 300 g and pressures of 100 atmospheres in Venus. Not only is it plausible that you have survived. The space historian Pavel Shubin believes that, if he is intact, could be found floating In the ocean.

Alzheimer’s starts long before its symptoms. And we have discovered one of its first mechanisms

by

We generally associate Alzheimer’s disease with memory loss since this is probably its most visible symptom. However, it is still what we do not know about the biological processes that unleash these symptoms. Piece by piece, we are solving this immense puzzle. New mechanism. A team in which researchers from the Severo Ochoa Molecular Biology Center (CBM-CSIC-UAM) participate He has discovered A mechanism linked to the early development of Alzheimer’s disease. The key component of this mechanism is in a protein called SFRP1. Astrocytes and SFRP1. As described by the team responsible for the finding, in the origin of the mechanism are brain cells called astrocytes. Astrocytes They are glial cells (A type of nerve cell) that for a while we thought were “assistants” of neurons but whose relevance we are seeing grow. In a mice -based model, the new study has shown that these cells could play an important role in the appearance of Alzheimer’s through an “excessive” production of the SFRP1 protein. This protein is one of the compounds involved in the regulation of communication between different cells during development, but in later stages of life its excess may imply risks. A “jam” in the brain. As the equipment continues, the accumulation of the SFRP1 protein in the adult brain is associated with chronic inflammatory processes associated with aging, and also to Alzheimer’s own disease. The problem arises when this excess blocks the activity of the adam10 enzyme, which plays a key role in maintaining the proper functioning of neuronal connections. “This blockage generates an imbalance that deteriorates synaptic plasticity, an essential cell mechanism to form and consolidate memories that allows neurons to regulate their connectivity in response to different stimuli,” They explain in a press release. Long -term synaptic potentiation. The accumulation of the SFRP1 protein would thus be interfering with a process called LTP or long -term synaptic potentiation. This is a “fundamental” process for learning and memory, the team stands out. A vital process in brain plasticity, that is, that allows the neuronal connections that are most frequently used to be reinforced, something indispensable when consolidating new memories. The details of the study have been published In an article In the magazine Cell Reports. A possible trigger. The fight against Alzheimer’s is a fight against the clock. The appearance of its most easily noticeable effects is associated with lesions already irreversible in the brain, so the only remaining route of action is to delay the advance of the disease. The techniques focused on detecting the internal signs of the disease, mainly the accumulation of amyloid plaques in the brain can allow us to advance ourselves to the appearance of the external symptoms of the disease. Now, the new study Open a road To get into stages still prior to the disease. “The increase of SFRP1 in early stages seems to act as an active engine of pathology, not as a simple companion of other degenerative processes,” Explain in the press release Guadalupe Pereyra, co -author of the study. Beyond rodents. Like any study in mice, extrapolating its conclusions can be complicated, so studies that validate what you have learned and the degree to which it is applicable to the development of the disease in humans will be needed. Converting what has learned into new therapeutic pathways will not be simple either, but this type of advance can help us in different ways. First, because understanding the disease and its mechanisms is essential in order to find a future cure; and second, since in the fight against their symptoms, Early detection It is a very important advantage.

IBM fired 8,000 workers to replace them with AI. What I did not expect was to hire many others … for the AI

by

The chickens that enter through the chickens that come out. IBM was one of the main protagonists in the Waves of mass layoffs globally Two years ago, and now it is again for the consequence of making this decision: having even more workers. The layoffs. In January 2023 IBM joined the Gray days In the technological sector. Google announced the departure of 12,000 of its employeesX (old twitter) fired 83% of its workforce in Spainand Spotify said goodbye to 600 workers. On the IBM side, I know They completely paralyzed hiring and the dismissal of 7,800 workers was formalized. IBM CEO itself explained That his company would cover artificial intelligence, affirming at least 30% of its workforce was replaceable. The consequences. IBM talked about how they could do without workers by replacing them for AI, but not about the people necessary to operate that AI. One of the executive directors of the technology, Arvind Krishna, collects to WSJ that the number of employees has increased after the wave of layoffs. “Although we have done a huge amount of work within IBM to take advantage of AI and automation in certain business workflows, our total employment has actually risen, because we have managed to obtain more investment capacity to cover other areas,” Krishna told The Wall Street Journal. The company has fired workers to replace them with artificial intelligence, but has also increased hiring in programmers and sales personnel. They have not transcended concrete numbers about how many hiring there have been and if they have really covered or not the 7,800 layoffs. The automation to command. IBM has been fully trusting more than three years Askhran artificial intelligence solution that began to take shape in 2021 and that Today they use for processes related to human resources management (payrolls, employee documentation, vacation managed). The company claims to have automated 94% of RRHH’s routine tasks, achieving productive improvements worth 3.5 billion dollars in recent years in more than 70 business areas. This significant saving in human resources, according to the company, is allowing them to invest in other areas. An AI-FIRST company. On the IBM website we have detailed The official position of the company with AI. It is worthy of a Black Mirror chapter, but perfectly summarizes the state of AI in the workplace. “As the chatbot learned and became smarter, our NPS (Net Promoter Score) began to increase. We added more functionalities, along with the ability to perform transactions. Askhr evolved to a digital assistant that allowed managers to transfer employees to another manager or initiate the quarterly promotion process. Everything was done directly in Askhr With just a few clicks. In 2024, Askhr He managed more than 11.5 million interactions; 94% of them were resolved within the platform. That means that, of all the questions asked, only 6% needed to be derived from Askhr To a specialized partner in HR. The current NPS is +74, so we have traveled a long way from that -35. There are almost 90 automation integrated into Askhrand more on their way. Thanks to this, managers can make HR transactions 75% faster than before. According to IMB, automating processes with AI has allowed you to be faster and more efficient, with a minimum need to derive HR personnel processes. One of the keys is in the evolution of the assistant: they have been using it in tests since 2017, and in 2025 it is already replacing humans. IBM is not alone. The companies replacing workers for AI was not an experiment of 2023. There are already companies that have dispensed with 90% of their customer service departments by Chatbots, ensuring that it was the right decision. Duolingo started 2025 With replacement of human teamsome already shot them through the cylinder head and They ended looking for programmers on LinkedIn. AI and its labor impact It is especially linked to process automation. Reports like ‘The Future of Jobs Report 2025’prepared by World Economic Forum, hope that by 2030 the Process automation destroy about 92 million jobs.

The obsession with flat belly and radical thinness

by

As every summer, aesthetic pressure marks the pattern again, and this year social networks have found a new goal: the flat belly. Although it seemed that the ideal of the perfect body It was fadingthe viral content has demonstrated otherwise Social networks mark the pattern. A movement It has emerged under the name of “average complexion”. In many videos It can be observed To people, mostly women, showing their body under the pretext of being “neither skinny nor fat”, thus perpetuating unrealistic beauty standards. Influencers Like Carla Flila They have pointed out That this type of content “only generates unnecessary insecurities” by promoting a standard that, far from being inclusive, continues to be exclusive and harmful. Beyond Trend. This phenomenon is nothing more than the tip of the iceberg, since There are many other videos how to “deflate the belly” or “routines to have flat belly.” In them you can visualize express exercises, miraculous diets and advice without scientific basis. All for the insatiable search for an ideal of beauty: the flat belly. Deeper. But what seems like a simple aesthetic tendency has deeper repercussions. A study by the University of Malaga analyzed How within the apparently harmless content you can find publications that actively encourage eating disorders. This duality has highlighted how difficult it can be to distinguish between content that simply promotes exercise and one that, under the disguise of healthy recommendations, encourages dangerous food behaviors. In addition, other research published in Behavioral Psychology showed How brief exposure to representative images of the ideal of thinness has a negative effect on the self -esteem of the participants, increasing anxiety. A persistent stigma. And if the discourse in networks reinforces little inclusive standards, Gordophobia continues to feed body dissatisfaction from another front. A recent UNIR report entitled “Between the healthy and the cult of the body”He revealed that 43.8 % of the boys and 34.7 % of the girls have high levels of Gordophobia. In fact, such as They have detailed In CTXT, Gordophobia is not an isolated prejudice, but a tool that keeps people in a state of constant body dissatisfaction, promoting harmful behaviors for physical and mental health. An endless cycle. This aesthetic pressure is not a new phenomenon. For centuries, the bodies have been molded and controlled by the prevailing aesthetic ideals. The idea of ​​a flat belly in the most recent history began in the nineteenth century, when women They were pushed To use Corsés to get the iconic “Wasp waist”, a symbol of femininity that deformed its ribs and hindered breathing. Almost arriving at this century, in the 90s and early 2000s, the beauty ideal turned towards extreme thinness, popularized by models such as Kate Moss and the call “Heroin Chic“Today, social networks have taken over, perpetuating that cycle of unattainable standards that transform bodies into shaped objects. Outside the networks. Aesthetic standards seem to take another way again, have we returned 20 years ago? The issue is that after a parenthesis in the 2010 decade marked by the rise of movement “POSITIVE BODY“, which included a diversity of bodies, now fashion derives Towards extreme thinness. With the reappearance of the Victoria’s Secret parade, which has bet again by hyperdelled models after years of criticism for their lack of diversity, as well as The reintroduction Of aesthetics and 2k in haute couture brands, they make it clear where the aesthetics wants to return. While social networks continue to amplify these restrictive canons, it is worth asking what will be the impact on the mental and physical health of those who are dragged to pursue unattainable aesthetic standards.

The photovoltaic industry has entered its self -replicating phase

by

Maximize the performance of solar panels is one of the great challenges of Photovoltaic industry. But it is something that is not limited to make more efficient panelsbut to engineer ways that they stay clean for longer. Because the great enemy of the panels are not the clouds, but dust or snow. Cleaning these homemade panels is clue For three reasons. The first is that a clean panel is more efficient. According to estimatesa dirty panel produces up to 39% less a year. The useful life of them increases because corrosion and other damages are avoided and, as more electricity generates, production is optimized and the Investment return. There is robots designed to clean them And we have seen them in all shapes and sizes, even tractors manually operated with a roller that rubs the surface of the panels, but one of the challenges is how to optimize the cleaning of the panels in the huge ‘farm’ installed in deserts such as Chili, China either India. And the answer is another robot, but not anyone: a robot that in turn is a solar panel. Solar panels that clean solar panels that clean … Be more or less autonomous, robots need energy to work. It can be through long cables that feed them or by batteries in the longest facilities, so when they are not cleaning, they are wasting time. Especially in desert scenarios in which dust is a problem. And the sauce of this matter is the following video: What we see in Action is a robot of the Chinese company Sunpure, a company that has specialized precisely in the creation of devices to clean solar panels. Beyond the conventional ones, they have two models that have a solar panel in the upper part that is the one that provides energy so that the rollers work and can give the necessary passes by the rows of panels. One is that of the upper video, called Venus, another is the one that we leave below: The difference between this and Venus is that the new robot has more upper surface occupied by the solar food panel, seems more adaptable to different panel sizes and, above all, is easier to clean. The reason? When it reaches the end of the row, a brush awaits you that passes the panel of the robot itself, cleaning the dust that may have accumulated. This cleaner robot has already been installed in some photovoltaic plants, such as those of India or Uzbekistan, and the previous model is the one that works cleaning The CME1 panels, the largest photovoltaic plant in Chile In the Atacama desert. They are curious, but beyond that, this type of robots is a necessity. Equipo them with solar panels is a good idea that they can perform those cleaning tasks in locations in which dust is a problem. In fact, those of this company are working, above all, in plants installed in deserts. Now, the great step of the industry both in the face of mass production and the most homemade is the creation of self -impossible solar panels. It is something that is already working on, with advances as interesting as that of the Startup Sol Clarity, a company derived from the University of Boston. Baptized as electrodynamic scren, it is a very thin and transparent sheet that Load dust particles with static And, when he has caught them, the ‘sweep’ using electromagnetic waves. It is a good solution not to depend on robots and not be the black water hole which is the current cleaning of large -scale solar panels. And in a sector in which every kilowatt counts, that they are as clean as possible. Images and videos | Sunpure In Xataka | I thought the robots could no longer surprise me.

You can use your Displayport 1.4 cable (or HDMI 2.1 if you use consoles) without any problem and the experience will be very good. Moreover, you are quite likely to be forced to do so because one of the great inconveniences of UHBR20 is the one that cable is one meter. Just have the tower on the ground so that the cable does not arrive. The thickness of the rear is explained in a quite simple way: the power supply is integrated into the chassis and it was not | Image: Xataka But let’s talk about the screen. This monitor mounts A third generation QD-OED panel Manufactured by Samsung. It has a diagonal of 26.5 inches, 240 Hz of refreshment and 4K resolution (3,840 x 2,160 pixels), so we are talking about a density of 166 pixels per inch. It is an absolute barbarity and translates into several things, but what we are going to notice with the naked eye is the sharpness of the texts. The QD-OED panels They have a problem and that is that the separation between the pixels derived from their matrix can cause a kind of aberration to appear in high contrast areas. For example, on the edge of a black text on a white background we will see a finite pink line. That is solved with a greater resolution and that is what happens in this case. This effect disappears completely on this monitor. We will notice if we zoom and physically approach the screen, but it is not something that we are going to do on a day -to -day basis.

The Anti -Capa does a quite a good job in general, but nothing can with the brightness of a window located just in front of the monitor or a strong light source on the sides, as is my case. I have a window just behind and, even if it hides well, I can appreciate it. That said, the antiglare layer works well, but does not magic. As for the sprocket of the monitor, we are talking about 250 nits in SDR, 450 nits in True Black 400 and up to 1,000 nits (in a reduced percentage of the screen) activating the Peak 1000 mode. We can also alternate between templates for the SRGB, Delta P3 and Adobe RGB color spaces. I recommend True Black 400 for general use, but Peak 1000 gets brutal quality, especially if our room … Read more

The battery quality in mobiles

by

I have interviewed enough brand leaders to have something very clear: the battery is one of the characteristics that most influences the purchase of a smartphone. In Europe we seemed doomed to a very specific figure: about 5,000mAh that remained immutable generation after generation. Chinese mobiles have begun to mark a trend with 6,000mahbreaking it in specific cases such as the Redmagic 10 Pro with its 7,000mah or the recent one Honor Power, with 8,000mah. In addition to the clear war in relation to the milliamps-Hora this eagerness for Chinese manufacturers to bring the best batteries goes further: the focus is in their quality and usability. Crazy about capacity. Broken the 6,000th barrier, we published a piece that has not taken long to materialize: one regarding that this roof surpassed, We don’t know where the limit is. Honor has already managed to introduce 8,000mah On a phone with an 8mm thickness, the same of any other traditional smartphone. Realme rises to 10,000mahabsolute madness. From one year to another, the 5,000mAh of the competition have become an obsolete figure, although everything that shines is not gold. A change in industry. That this capacity has been unlocked has a main responsible: the Silicon-Carbon batteries. Here manufacturers have been pioneers by introducing this technology, which allows you to introduce much more energy capacity in the same size. From a time to this part, this type of batteries has become more and more popular, although some manufacturers (including the Chinese) They reserve them for China for a simple reason: costs. Beyond silicon. Longevity is another obsessions for this 2025, and OnePlus is the best example. His OnePlus 13t It is able to function without using battery, but electric current, when plugged in the current. This function, which we already saw in the past in Redmagic mobiles (and Sony already flirted with it in some Xperia), is ideal to preserve the life of the battery on the scenario that suffers the most: when it is connected to the current making discharge cycles. A perfect ally. A good part of the responsibility in these advances has it Catlone of the giants in the battery industry (mainly in the industrial and electric car spheres). In recent years, Catl has collaborated with manufacturers such as Realme for the joint development of batteries, betting on silicon-carbon as material. A dart to the rest of the manufacturers. The 6,000 (or more) MAH are becoming a standard, and now the glove will have to pick it up the rest of manufacturers outside China. Betting on this type of batteries is not cheap, but launching a terminal with a 5,000mAh battery will begin to become a competitive disadvantage for the rest.
