The impact of electrolytes and separators on safety is mainly due to their characteristics.

The flammability and liquid state of widely used commercial electrolytes are not particularly ideal choices for safety. If lithium-ion conductivity is used σ A solid electrolyte with Li+>104Scm1 can, on the one hand, prevent lithium dendrites from piercing the separator and reaching the positive electrode, thereby solving safety issues, and on the other hand, it can also solve stability problems that arise when the negative electrode comes into contact with carbonate electrolyte and the positive electrode comes into contact with aqueous electrolyte. Of course, by using an electrolyte with a wider electrochemical window (especially a higher LUMO) and adding some flame-retardant materials to the electrolyte, the mixed ionic and organic liquid electrolytes can be modified into a non flammable electrolyte (while maintaining ion conductivity) σ Li will not reduce it too much, and other means can effectively improve security.

The mechanical strength (tensile and puncture resistance), porosity, and whether the diaphragm has a closing function are important factors that determine its safety.
