  • Patent number: 10186732
    Abstract: A nonaqueous electrolyte solution for secondary batteries, which maintains small internal resistance and high electrical capacitance in long-term use in a nonaqueous electrolyte secondary battery uses, as an active material, a crystalline carbon material having a high crystallinity, and a negative electrode produced using a polymeric carboxylic compound as a binding agent. The nonaqueous electrolyte solution contains: (A) at least one compound selected from a group consisting of an unsaturated phosphate ester compound represented by a general formula (1) and an unsaturated phosphate ester compound represented by a general formula (2); (B) at least one compound selected from a group consisting of a sulfite ester compound, a sulfonate ester compound, an alkali metal imide salt compound, a fluorosilane compound, an organic disilane compound or an organic disiloxane compound; (C) an organic solvent, and (D) an electrolyte salt. A secondary battery using such nonaqueous electrolyte solution is also described.
