The present disclosure provides a non-aqueous electrolyte including an additive for a non-aqueous electrolyte, which is represented by the following Chemical Formula 1:




In Chemical Formula 1, R1 to R5 are each independently any one selected from the group consisting of H, an alkyl group having 1 to 10 carbon atoms, and an alkoxy group having 1 to 10 carbon atoms, and R may be an aliphatic unsaturated hydrocarbon group having 2 to 10 carbon atoms, or —OR′ (R′ is an aliphatic unsaturated hydrocarbon group having 2 to 10 carbon atoms).
