Since the advent of the solid-state batteries,employing solid polymer electrolytes(SPEs)to replace rou-tine flammable liquid electrolytes is regarded to be one of the most promising solutions in pursing high-energy-density battery systems.SPEs with superior thermal stability,good processability,and high mechanical modulus obtain increasing attentions.However,SPE-based batteries are not impenetrable due to their decomposition and combustibility under extreme conditions.Researchers believe incorporat-ing appropriate flame-retardant additives/solvents/fragments into SPEs can intrinsically reduce their flammability to solve the battery safety issues.In this review,the recent research progress of incom-bustible SPEs,with special emphasis on flame-retardant structural design,is summarized.Specifically,a brief introduction of flame-retardant mechanism,evaluation index for safety of SPEs,and a detailed overview of the latest advances on diverse-types SPEs in various battery systems are highlighted.The deep insight into thermal runaway process,the free-standing incombustible GPEs,and the rational design of pouch cell structures may be the main directions to motivate revolutionary next-generation for safety batteries.
