Abstract

Abstract: In order to explorer the thermal runaway process of Li-ion batteries, based on the research and establishment of the Li-ion batteries thermal runaway method, the thermal runaway phenomenon of 18650 Li-ion batteries was analyzed by electrical heating trigger under different charging states, The gas leaked through thermal runaway process was both collected and analyzed. The results show that the electrical heating method can triggering the thermal runaway of 18650 Li-ion batteries, which will produce toxic gases, accompanied with smoke and high temperature. Improper protection will cause harm to human body and environment.

Key words: Li-ion battery, thermal runaway, electrical heating trigger
