【 摘 要 】

Electrochemical cell performances of fluorinated natural graphite (abbreviated as FNG) electrode material was studied by using 1M of LiClO4- EC : DEC : PC (1 : 1 : 1 v%) electrolyte solution with and without 0.15% v/v fluorinated carboxylic ester additive difluoromethyl acetate-CHF2COOCH3 (MFA) at -10°C. The electrochemical cell performances were studied by cyclic voltammetry, galvanostatic charge-discharge and impedance analysis. The additive has proven its positive role with the electrolyte system and has shown the improved characterization over the blank electrolyte system.
