The invention discloses a propylene carbonate-based electrolyte and a lithium ion battery containing the electrolyte. The electrolyte comprises a propylene carbonate solvent, a lithium salt and a diluent, and the diluent is a weakly polar chain solvent. The diluent is trimethyl borate, triethyl borate, tripropyl borate, dimethyl carbonate, diethyl carbonate, ethyl methyl carbonate, methyl butyl ether, ethyl butyl ether, propyl butyl ether , one or more of methyl ethyl ether and ethylene glycol dimethyl ether. The propylene carbonate-based electrolyte of the present invention and the lithium ion battery comprising the electrolysis have the characteristics of high electrical conductivity, excellent low temperature performance and good high pressure stability. |
