摘　　要：The rapid development of lithium-ion batteries(LIBs)is faced with challenge of its safety bottleneck,calling for design and chemistry innovations.Among the proposed strategies,the development of solid-state batteries(SSBs)seems the most promising solution,but to date no practical SSB has been in large-scale application.Practical safety performance of SSBs is also challenged.In this article,a brief review on LIB safety issue is made and the safety short boards of LIBs are emphasized.A systematic safety design in quasi-SSB chemistry is proposed to conquer the intrinsic safety weak points of LIBs and the effects are accessed based on existing studies.It is believed that a systematic and targeted solution in SSB chemistry design can effectively improve the battery safety,promoting larger-scale application of LIBs.
