For car companies, new battery technologies such as solid-state batteries are a double-edged sword. On the one hand, the new battery technology has many performance advantages such as higher energy density, and the first layout may become the first person to eat crabs; on the other hand, the high R&D cost and long effective period of the new battery technology are important for new car companies. It is said that some of the gains outweigh the losses. In addition, the industrialization of forward-looking technologies is also extremely risky.

　　This highly anticipated "China Tesla" is equipped with a 70-kilowatt-hour liquid-cooled constant temperature battery pack that uses high-energy-density VDA automotive-grade square shell batteries with a cycle life of up to 2000 times and a vehicle wind resistance as low as 0.29. The maximum cruising range at a constant speed of 60km/h exceeds 500km, and the NEDC comprehensive working condition is 355km.

　　It is worth mentioning that in terms of power batteries, NIO not only chooses the most advanced lithium battery unicorn Ningde Times as the battery supplier, but also actively deploys new battery technology. There are only 4 solid-state battery patents published.

　　Solid-state batteries, in simple terms, use solid electrolytes to increase the voltage platform and further increase the energy density of the battery; on the other hand, the solid-solid reaction can reduce gas emissions and improve the safety performance of lithium batteries. Among the many new battery technologies, solid-state batteries are known as the most reliable next-generation lithium battery technology.

　　As the most popular emerging car maker and the newest battery technology closest to industrialization, NIO is actively deploying solid-state batteries, which can easily make people think that "emerging car companies should choose new battery technology". But in fact, not all emerging car-making forces have spent a lot of energy betting on next-generation battery technology like Weilai.

　　Industry insiders pointed out that for car companies, new battery technologies such as solid-state batteries are a double-edged sword. On the one hand, the new battery technology has many performance advantages such as higher energy density, and the first layout may become the first person to eat crabs; on the other hand, the high R&D cost and long effective period of the new battery technology are important for new car companies. It is said that some of the gains outweigh the losses. In addition, the industrialization of forward-looking technologies is also extremely risky.

　　Therefore, for new battery technology, the choices of emerging carmakers are actually quite conservative.

　　Dr. Xu Huanxin, chief operating officer of Weimar Motors, said that the requirements of car companies for battery technology are actually very simple, one is the improvement of energy density, and the other is the guarantee of safety performance. Battery technology is a relatively open thing. In the end, it is still uncertain who will die. The cooperation between Weimar and some companies engaged in forward-looking battery technology is more of an exploratory nature.
