| 主权项 | 1. An electrochemical device comprising: an anode, a cathode, and a non-aqueous electrolyte; wherein the non-aqueous electrolyte comprises 1 wt % to 2 wt % of an aliphatic di-nitrile compound based on the weight of a non-aqueous electrolyte, 1 wt % to 10 wt % of fluorethylene carbonate based on the weight of a non-aqueous electrolyte, a lithium salt and a solvent, wherein the solvent consists of one or more cyclic carbonate selected from the group consisting of ethylene carbonate (EC) and propylene carbonate (PC), and a linear carbonate, wherein the aliphatic di-nitrile compound is represented by Formula 2: N≡C—R—C≡N [Formula 2] wherein R is (CH2)n, wherein n is an integer of 2 to 12. | ||
