html July 21st news, NIO officially announced that is scheduled to start delivering 150kWh solid-state battery in the fourth quarter of 2022, and the monomer energy density can reach 360Wh/kg. By then, the new future ES8 battery life can reach 850km, the ES6 battery life can reach 900km, and the ET7 will exceed 1000km, helping users get rid of battery life anxiety.

When NIO launched the ET7 and autonomous driving NAD system last year, it also brought the first 150kWh solid-state battery. This should be the most powerful car battery with the highest capacity so far, or a product equipped with mass-produced models. In terms of capacity and battery form, it has reached the first-class level in the industry.
official introduction said that is a solid-state battery that uses ultra-high nickel positive electrode, prelithiated silicon carbon negative electrode and solid electrolyte (including solid and liquid). There is still a part of the liquid electrolyte left inside the battery. Strictly speaking, it should be considered a semi-solid battery. It is a transitional product of the evolution of liquid batteries to solid batteries. But even so, its performance parameters are already eye-catching enough, surpassing most lithium-ion battery on the market.

Kylin battery released by CATL , as well as Tesla self-developed 4680 battery, should be one of the most outstanding power battery products at present. The former battery pack has an energy density of 255Wh/kg and a volume utilization rate of up to 72%; the latter has a slightly lower volume utilization rate of only 62%, but the energy density of a single cell reaches 300Wh/kg, and its performance parameters are also ahead of most power batteries on the market.
But even so, they are still slightly worse than NIO's solid-state batteries. In terms of energy density alone, NIO is 20% higher than Tesla. Moreover, the total capacity of its battery pack reaches 150kWh, which is the capacity that most electric vehicles cannot reach at present. Tesla Model Y has a battery capacity of 77kWh, bringing 525km of battery life. Most of the battery capacity of other brands of electric vehicles is around 70kWh, and few of them exceed 100kWh. NIO is indeed too far ahead in this regard.

Of course, the battery capacity is larger and the weight will increase a lot, which will in turn affect the car's range. Therefore, the specific size of battery packs to be assembled on the car requires different plans to be formulated according to different models. However, NIO did show off her muscles this time and would not be behind in the battery technology arms race. Xiao Lei boldly speculated that will see a large number of new cars with a range of over 1,000km on the market next year. If it does not reach this range, I guess I would be embarrassed to call it a high-end electric car.
