Original Abstract Submitted

A method for manufacturing a lithium-ion rechargeable battery includes manufacturing a positive electrode plate that includes a positive electrode mixture layer containing a positive electrode active material, lithium hydroxide, and lithium acetate; manufacturing a negative electrode plate that includes a negative electrode mixture layer containing a negative electrode active material and a sodium salt; and injecting a non-aqueous electrolyte solution including LiBOB into a case that accommodates the positive and negative plates. When “A” represents a mole number of the lithium hydroxide added in the manufacturing the positive electrode plate, “B” represents a mole number of the lithium acetate formed in the manufacturing the positive electrode plate, and “C” represents a mole number of the sodium salt added in the manufacturing the negative electrode plate, 0.04≤B/A≤0.06 and 1.9≤B/C are satisfied. Lithium acetate has a higher solubility in the non-aqueous electrolyte solution than sodium acetate.
