About Thermal Runaway of Power Lithium-ion Battery
Thanks to the warm attention of new energy, the power lithium-ion battery industry has also attracted much attention. Power lithium-ion battery is the power source for tools to supply power. It mostly supplies power for electric vehicles, electric bus, electric bicycles and sightseeing car. Focusing on the thermal runaway of power lithium-ion battery (mainly high-temperature thermal runaway), this paper discusses various factors affecting the safety of lithium-ion battery, and how to further improve the safety of lithium-ion battery. Three causes of thermal runaway of power lithium ion battery, and some treatment methods and suggestions are put forward. Heat inducement Usually, thermal inducement is power battery work in the high-temperature environment, including external fire, poor battery heat dissipation, etc. At external high temperature, due to the structural characteristics of lithium-ion battery, SEI membrane and electrolyte will have analytical react...
