Cathode, anode, and electrolyte exhibit a vapor pressure of less than 0.01 kPa, a vapor pressure of less than 60% of the vapor pressure of the liquid solvent alone, a flash point of at least 20 degrees Celsius higher than the flash point of the liquid solvent alone, a flash point higher than 150 ° C. or no flash point. Nonflammable semisolid electrolytes containing lithium salt dissolved in a mixture of liquid additive and liquid solvent having a salt concentration of 1.5 M to 5.0 M, wherein the liquid additive is hydrofluoro ether (HFE), trifluoro propylene carbonate (FPC), methyl nonafluorobutyl ether (MFE), fluoroethylene carbonate (FEC), tris (trimethylsilyl) phosphite (TTSPi), triallyl phosphate (TAP), ethylene sulfate (DTD), 1,3- Propane sultone (PS), propene sultone (PES), diethyl carbonate (DEC), alkylsiloxanes (Si-O), alkylsilanes (Si-C), liquid oligomeric siloxanes (-Si-O-Si-), Tetraethylene glycol di Butyl ether (TEGDME), or, rechargeable lithium battery is selected from a combination of the two. |
