摘要： A method of producing a lithium ion secondary battery includes: selecting a positive electrode active material that has a prescribed specific surface area, and preparing a nonaqueous electrolyte solution that contains a compound with a following formula (1) at a prescribed concentration. In an xy-coordinate plane that gives a relationship between a specific surface area x [m2/g] of the positive electrode active material and a concentration y [mol/kg] of the compound in the nonaqueous electrolyte solution, a combination of the prescribed specific surface area and the prescribed concentration corresponds to a combination of values that lies within a hexagonal inner region formed by connecting 6 points (x, y)=(0.80, 0.035), (2.20, 0.05), (2.60, 0.10), (2.60, 0.16), (0.80, 0.16), and (0.50, 0.10) in this sequence with straight lines.
