摘要

Li-ion batteries (LIBs) that promise both safety and high energy density arecritical for a new-energy future. However, recent studies on battery thermalrunaway (TR) suggest that the higher the energy is compressed in a battery,the thermal accidents with fires and explosions can occur in a morecatastrophic way. This “trade-off” between energy density and safety poseschallenging obstacles toward the future applications of the developinghigh-energy chemistries. Herein, the thermal studies on the most appealinghigh-energy (HE)-LIB chemistries are carefully reviewed. The TR characters ofthe HE-LIBs, the material thermal failure behaviors as well as the underneathreaction mechanisms, and the most advanced TR mitigation technologiesare comprehensively summarized. Moreover, the effectiveness of differentTR mitigation routes is analyzed. Based on the analysis, the main challengesfor TR mitigation in HE chemistries are further explained. Finally, opinionson the future TR mechanism studies and the promising safety design routesto overcome this intrinsic “trade-off” between high energy and safety arepresented.
