Abstract

An electrolyte including a dinitrile compound, a trinitrile compound, and propyl propionate. Based on the total weight of the electrolyte, the weight percentage of the dinitrile compound is X, the weight percentage of the trinitrile compound is Y, and the weight percentage of the propyl propionate is Z, wherein, about 2 wt %≤(X+Y)≤about 11 wt %, about 1≤(X/Y)≤about 6, about 40 wt %≤Z≤about 50 wt %, and about 0.01<(Y/Z)≤about 0.3; wherein the trinitrile compound comprises at least one selected from the group consisting of 1,3,5-pentanetricarbonitrile; 1,2,3-propanetrinitrile, 1,3,6-hexanetricarbonitrile; 1,2,6-hexanetricarbonitrile, 1,2,3-tris(2-cyanoethoxy)propane; 1,2,4-tris(2-cyanoethoxy)butane, 1,1,1-tris(cyanoethoxymethylene)ethane, 1,1,1-tris(cyanoethoxymethylene)propane, 3-methyl-1,3,5-tris(cyanoethoxy)pentane, 1,2,7-tris(cyanoethoxy)heptane, 1,2,6-tris(cyanoethoxy)hexane, and 1,2,5-tris(cyanoethoxy)pentane.
