  • Non-Aqueous Electrolyte Solution and Secondary Battery
    Publication number: 20250062412
    Abstract: A non-aqueous electrolyte is provided and includes an electrolyte salt, a non-aqueous organic solvent, and an additive. The non-aqueous organic solvent includes a carboxylate, and the additive comprises a compound represented by formula 1: where n is 0 or 1, A is selected from C or O, X is selected from R1 and R2 are each independently selected from H, R1 and R2 are not selected from H simultaneously, and X, R1 and R2 at least contain one sulfur atom. The non-aqueous electrolyte satisfies following conditions: 0.02?an/m?9, 0.01%?a?5%, 5%?m?70%, and 8%?n?25%; where a is a mass percentage content of the compound represented by the formula 1 in the non-aqueous electrolyte, in %; m is a mass percentage content of the carboxylate in the non-aqueous electrolyte, in %; and n is a mass percentage content of the electrolyte salt in the non-aqueous electrolyte, in %. A conductivity of the non-aqueous electrolyte at 25° C. is greater than or equal to 5 mS/cm.
