The picture shows a solid-state battery
The rapid popularization of electric vehicles, so that the earth's ecological environment has improved, but electric vehicles are not acceptable to everyone, one of the key reasons, is the problem of short range of electric vehicles, plaguing many car buyers, a Tesla car in the summer after full charge, can run 500 kilometers of mileage, and in the winter, electric vehicle endurance will be greatly shortened, and a charge will take at least 1 hour, some electric vehicle owners need to spend more time, to charge the car long wait, Restricts the daily travel of electric vehicle owners.
So the charging time of electric vehicles will be shortened, the mileage will be greatly improved, is whether electric vehicles can occupy the market on a large scale, fortunately in the domestic Kunshan Qingtao Energy Company, has developed advanced fast charging technology, this company said that in the near future, released a new solid-state battery, energy density of 368WH per kilogram, only need to charge 13 minutes can last 600 kilometers, it can be seen that China's vigorous development in battery technology, it seems that even the Japanese auto giants do not want to catch up.
Electric vehicles on the market, basically use liquid lithium-ion batteries, this battery has risks, first of all, it is easy to cause safety problems, followed by the limited energy density of this battery, when the energy density of the battery per kilogram reaches 300WH, it has reached the technical bottleneck, the greater the energy density of the battery, in order to let the car travel a longer distance, it is the energy density of the battery that determines the endurance of electric vehicles, so the use of solid-state batteries is the best way to improve the mileage of the car at present.
Solid-state batteries can be used as the ideal type of car tram, the negative electrode material of this battery can use nano-silicon and graphite, the positive electrode can be used lithium-rich manganese-based materials, the energy density of the battery can easily exceed 300WH per kilogram, up to 450WH, this improvement has been about 20% of the existing electric vehicle battery performance, before GAC has released its new solid-state battery, can achieve a maximum of 1000 kilometers of endurance, the improvement of endurance will make electric vehicles more popular in the market.
Battery fast charging technology in the application of mobile phones has been very popular, some mobile phones can be fully charged in 15 minutes, in fact, this technology can also be applied to car charging, such as kunshan Qingtao Energy company released data, the company is about to release the solid-state battery, the maximum mileage is also 1000 kilometers, the fastest 13 minutes can be charged into 60% of the power, 600 kilometers of cruising range, has been able to meet the vast majority of needs on the high-speed car owners, even if traffic jams occur in winter, There is no need to worry about the problem of turning on the air conditioner and charging electricity.
Energy vehicles are the highlight of the country's new energy development, so the domestic electric vehicle technology has been at the global leading level, although Tesla motors are currently the leader in the field of electric vehicles, but the electric bus and other large electric vehicle market has been occupied by China, with the domestic technology of innovation, the future in the field of electric vehicles, Chinese car manufacturers will have enough strength and capital, and Tesla to launch a market competition, as long as the car charging time is fast enough, the mileage is far enough, not to worry about market sales.
