  • Nonaqueous electrolyte secondary battery and method for manufacturing the same
    Patent number: 10985400
    Abstract: A method for manufacturing a nonaqueous electrolyte secondary battery which includes an electrode assembly, a housing with an opening and contains the electrode assembly, and a sealing member sealing the opening, the electrode assembly comprising a positive electrode and a negative electrode. The positive electrode includes a positive electrode active material, lithium carbonate, and lithium phosphate, the negative electrode comprising a negative electrode active material. The method includes placing the electrode assembly in the housing, and placing a nonaqueous electrolyte containing lithium fluorosulfonate in the housing.
    Type: Grant
