Adding flame retardants to electrolytes or introducing the flame retarded structures to various polymeric matrices can attain the purpose of an improved fire-safety, but there is almost no positive contribution and even are many negative effects on the electrochemical performance of batteries due to chemical or/and physical incompatibility with electrolyte, …
With the wide application of lithium-ion batteries (LiBs), safety performance is an important constraint on the commercialization of large-scale, high-capacity LIBs. The main reason for the safety problem is that the electrolyte of LiBs is highly flammable, especially under high temperature and high voltage. It is an effective method to improve the safety of cells by …
