Problems solved by technology
[0004] However, due to the limited material system of the current lithium-ion battery, it is impossible to make the lithium-ion battery have good high and low temperature performance at the same time. At the same time, when the temperature of the lithium-ion battery is too high, the performance of the lithium-ion battery will deteriorate rapidly, and there may even be a safety hazard.
