The next generation of lithium ion batteries will be what kind of battery?

Source: 2020 - 03 - 30 14:03 hits: time of the next generation of lithium ion batteries will be what appearance? The answer to some of the great god is good, have plans of several skills development direction. I want to use a different perspective: I want to make a comment on the size of the lithium battery application category, I'm going to comment on the direction of the Angle of the application of different skills, and whether they can complete, to replace the current large-scale lithium-ion batteries used in these categories. At present the application of lithium electricity category first: electric vehicles, Coach/bus/other commercial vehicles) Low-speed electric bicycle/electric bicycle fixed energy storage ( Power plant) - Power grid, FM/peak valley to adjust consumer electronic (3 c ( Represented by mobile phone) If you review a few competitors: ( By passenger cars) , the electric car - > Basic is the direction of the high energy density is the main ( High nickel and silicon, everyone says so li-ion battery is still the main direction of the future) , reduce capital may be another direction ( Lithium electricity, high-performance lithium iron may return, in many of the original use it now, not filter) Lithium iron phosphate, and security must be the top priority, lithium electricity this a few direction will be I do what I can do. And response to the trend of ratio to + low cost, high safety, let's take a look at other skills: fuel cell computing ( Cost must be high, life also owe good, variable load operation ability is poor, more direction only to heavy trucks) ; These skills are the actual quality is not so good in the literature, the volume energy density, the car is more important, or even worse. The super capacitor? The energy density is too low; Polyvalent metal ion? In practice, they can produce many energy density and longevity? I said is practice, not electricity experiment. So overall, pure economic accounting, the influence of the power system, pricing mechanism, economic scale is the key, may have a variety of skills, but need to progress, ZhuoLu. Consumer electronics ( 3 c( Mobile phone) : consumer electronics capital is not sensitive, Relative) , but need real volume energy density is too high, so the lithium electricity is most expensive cobalt acid lithium unify the whole country, over the years the ternary battery low capital, also began to have a part of the shopping center ( As an acquaintance description: now more is just one part of the charging treasure class) 。 In the future, the energy density of the high capacity must still is the mainstream & gt; Lithium battery of lithium cobalt oxide will not change. If indeed, flexible battery skills developed, or an increase in demand scene, then there will be some of the new development and the use of solid/flexible skills. Metal hydrogen/air/fuel cell will only be used for segmentation basically similar to the external mobile emergency power category, if lithium sulfur can do a good job maybe for some of the volume energy density low place will be more useful, super capacitor ultra low energy density, but also has the advantages of quick charge) Also found that only a few special category, basic no other skills in this direction is often used. So in general, ratio of lithium, lithium cobalt oxide, is the main flow, three may have been involved in, solid also may be used. Lithium sulfur fuel cells may be found a niche application direction.
