Tesla uses Sanyo's lithium cobaltate battery, which is also the best lithium cobaltate battery in the world. However, if there are many batteries in series and parallel, it is easy to cause problems, and an explosion is a big problem, so Tesla has also burned several cars!
most other electric vehicles use batteries from Ferrous lithium phosphate, which is much safer, but the energy density is also low (the reason why Tesla is not used).
