Abstract:

Since its invention, the lithium-ion battery has been widely used in various aspects of human life due to its advantages of high-energy density and long cycle life, among others. However, the safety problem of the lithium-ion battery cannot be ignored. Accidents, such as fire hazards and explosions caused by the thermal runaway of a lithium-ion battery cause inevitable property loss and casualties. Hence, many researchers have been paying attention to the safety problems of the lithium-ion battery. This study analyzes existing early warming methods of the lithium-ion battery thermal runaway from characteristic parameters like temperature, resistance, voltage, and inside pressure and the produced gas of the batteries combined with the knowledge of thermal runaway, concludes the normal early warning methods, and performs analyzation and prospect of the development of future early battery warming methods.

Key words: lithium-ion battery, warning methods, characteristic parameters, temperature, characteristic gas
