Abstract:  Lithium-ion battery (LIBs) play a key role in development of Smart City. The commercial electrolyte always restricts application of LIBs due to low melting point and high resistance at low temperature. This paper first reviews the recent development of LIBs low-temperature electrolyte in the aspect of lithium-salt,solvents and additives. And proposes temperature is the critical factor for LIBs capabitity. The challenges and future trends of low-temperature electrolyte are also discussed. Low-temperature electrolyte lithium salts should be developed with new lithium salts system; Low-temperature electrolyte solvents should be developed with EC-PC blend system; Low-temperature electrolyte additives should be connected traditional organic additives with new additives.

Key words: lithium-ion batteries, low temperature, lithium salt, solvent, additives
