Abstract

A non-aqueous electrolyte includes (i) an inhibitor against a reaction between an anode and a linear ester; (ii) a mixed organic solvent containing cyclic carbonate and the linear ester; and (iii) an electrolyte salt, wherein the inhibitor is any one compound or a mixture of at least two compounds selected from the group consisting of cyclic carbonate with a vinyl group, fluorinated ethylene carbonate, vinylene carbonate, cyclic acid anhydride, a compound having a cyclic S═O group and an acrylate-based compound. Also, an electrochemical device includes a cathode, an anode and the above non-aqueous electrolyte.
