The related electrolyte in Li-ion cell comprises: medium electrolytic solution including lithium hexafluorophosphate and its solvent, vinylene carbonate, and cyclohexyl benzene. Wherein, the mass percent ratio is: vinylene carbonate: medium electrolytic solution = 0.5-3%, and cyclohexyl benzene: medium electrolytic solution = 2-7%. This invention can improve the overcharge and cycle performance. |
