Title:
METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2021089805
Kind Code:
A
Abstract:
To lower the low temperature resistance of a nonaqueous electrolyte secondary battery, and improve the endurance against a high-voltage condition.SOLUTION: Provided is a method for manufacturing a nonaqueous electrolyte secondary battery. The method comprises the steps of: preparing a nonaqueous electrolyte solution with a compound represented by the general formula (I), X(PO2Z2)n (I) (where X is selected from a group consisting of Li, K, Mg and Ca, Z is selected from a group consisting of H, CH3 and C2H5, n=1 when X is Li or K, and n=2 when X is Mg or Ca) added thereto; and encasing a positive electrode, a negative electrode and the nonaqueous electrolyte solution in a battery case.SELECTED DRAWING: Figure 1
