What problems are currently facing lithium batteries?

Battery technology has not yet made a breakthrough, but the breakthrough is a breakthrough, but when it will be used is still unknown. Previously, ARPA-E has supported more than 75 energy storage-related research projects, all of which have achieved some satisfactory results, but they have not yet made breakthrough progress in processing small-volume, low-cost energy storage equipment. . Although through hard work, many start-up companies are close to processing an energy storage device that integrates economy, safety, compactness and high energy density, and can reduce its cost to $100 per kilowatt-hour. But if the price of energy storage equipment is controlled at this level, it will inevitably lead to galvaniceffect (galvaniceffect, the so-called galvaniceffect refers to the local corrosion at the contact of dissimilar metals in the same medium due to the difference in corrosion potential) . Only renewable energy sources can solve this problem. They can make electric vehicles lighter and lower in cost, but there is a slot that they can’t overcome. Renewable energy is only available when the sun is shining or the wind is raging. Relatively stable. It is a pity that the commercialization speed of this new type of battery is far behind the human shift from fossil fuels to renewable energy. Even if it is as bold as Musk, it has to be admitted that the current electric vehicle manufacturers have not made much progress in improving lithium batteries. In fact, many researchers believe that in order to achieve leapfrog development, energy storage devices must break the existing barriers and adopt a new chemical process and physical shape. Only in this way can we get rid of the original architecture and break the domination of lithium batteries in consumer electronics, electric vehicles, and network-level storage systems in the past decade. In May of this year, the U.S. Department of Energy (DOE) held a seminar on the topic of Beyond Lithium Batteries. This is the ninth year of the seminar. Every year, researchers gather to discuss the development of new energy storage equipment. The technical challenges faced. Hu Qichao, the founder of SolidEnergySystems, has created a new type of lithium metal battery, which significantly improves the energy density of the battery, greatly surpassing existing products. At the seminar, Hu Qichao also talked about the development of a new type of lithium metal battery. He believed that the most important obstacle encountered in the research and development process that lasted for more than ten years was how to transform an idea into a product. This is even more difficult for the battery, because once you improve the performance of one aspect, it may affect the performance of the other. Therefore, difficult trade-offs and choices must be made. Serious shortage of Ru0026D funds Even if manufacturers can finally bring new technologies to the market, they will still face difficulties in expanding processing and finding buyers. The previous Leyden Energy and A123 system are the best negative teaching materials. Although they have new technologies in their hands, they still fail due to insufficient funds and unsatisfactory demand. In addition, two other startups, Seeo and Sakti3, have also become unlucky, and they were acquired at low prices before the new battery was mass-produced.
