Abstract Progress on the research of fire behavior and safe protection of lithium ion batteries (LIBs) is reviewed in this paper. Thermal runaway (TR) mechanism of LIB is revealed from the aspects of chemical reactions and heat accumulation. The fire behavior of high energy LIB is exhibited, and the TR propagations between cells and modules are discussed. This paper introduces the warning parameters and strategies of the fire prediction and early warning of LIB. Improving the inherent safety and suppressing the LIB fire effectively are still challenges at present. Some perspectives and outlooks on the future LIB safety researches are given.
