Abstract

Abstract:

The lithium-ion battery is one of the most widely used new energy batteries today. With the advantages of light weight, long life, high capacity and low pollution, it has been widely promoted and popularized, and especially plays a non-negligible role in electric vehicles, mobile communications, military equipment, drones and other fields. However, the lithium-ion battery poses significant safety hazards. The substance composition and improper use can easily lead to the thermal chemical reaction inside the lithium-ion battery, and cause the battery thermal runaway, which may cause the battery fire, or may even cause the equipment explosion, seriously affecting the users' life and property safety. Therefore, people attach great importance to the safety status assessment of the lithium-ion battery, and hope to comprehensively grasp the law of thermal runaway of the lithium-ion battery by analyzing the causes of its safety problems, and propose reliable early warning methods, in order to provide effective support for the safety application of the lithium ion battery in electric vehicles, energy storage power stations and other fields.

Key words: lithium-ion battery, thermal runaway, feature parameter early warning, safety status assessment
