What kind of battery will the next generation of lithium batteries be?

What will the next generation of lithium batteries look like? The answers of some great gods are good, and there are arrangements for the development of several skills. I want to use a different perspective: I want to make a comment on the size of the lithium battery application category, the application angle I want to comment on the direction of different skills, and whether they can be completed, replace the current large-scale application of lithium batteries in these categories . At present, the application category of lithium battery is the first: electric vehicles (buses/buses/other commercial vehicles) low-speed electric bicycles/electric bicycles fixed energy storage (power stations)-integrated into the grid, frequency modulation/peak and valley adjustment consumer electronics 3C (represented by mobile phones) If you comment on a few competitors: (by passenger cars), electric vehicles -> basically the direction of high energy density is important (high nickel, silicon, everyone says, so lithium batteries are still an important direction in the future), reduce Capital may become another direction (the high-performance lithium iron of lithium battery may return, in many original uses of it, not screening) lithium iron phosphate, and safety must be the top priority. These directions of lithium battery will be my best The trend that can be done. To deal with the trend of high specific energy + low cost + high safety, let us take a look at other techniques: fuel power battery calculation (the cost must be high, the lifespan is not good, the variable load operation ability is poor, and it can only be used for heavy duty Driving in the direction of the truck); the actual quality of these skills is not as good as in the literature, the volumetric energy density, which is more important for cars, and even worse. Supercapacitors? The energy density is too low; are polyvalent metal ions? How much energy density and lifetime can they appear in practice? I am talking about practice, not experimental electricity. So on the whole: purely economic accounting, affected by the pricing mechanism of the power system, the economic ratio is the key, and various skills may be available, but they must be improved. Consumer electronics (3c (mobile phone): The capital of consumer electronics products is not sensitive (relatively), but the real volume energy density is too high, so lithium batteries are the most expensive lithium cobalt oxide to dominate the world. In recent years, the capital of ternary batteries has been low, and At the beginning, there was a part of a shopping mall (as an acquaintance described: now it is more of a part of the power bank). In the future, the high-capacity energy density must still be the mainstream>The lithium cobalt oxide of lithium batteries will not change. If flexible battery skills are indeed developed or demand scenarios are added, then there will be some new developments and the use of solid/flexible skills. Metal hydrogen/air/fuel power batteries will basically only be used for subdivision Similar to the category of external mobile emergency power supplies, if lithium-sulfur can be done well, it may be more useful for some places with low volumetric energy density.Supercapacitors have ultra-low energy density, but also have the advantage of fast charging.)It will also find that there are only a few special categories. Basically no other skills are often used in this direction. So in general: high specific energy lithium, that is, lithium cobalt oxide, is an important flow, three may have been involved, and solids may also be used. Lithium-sulfur fuel power cells may only find a niche application direction. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
