Abstract:
A nonaqueous electrolyte secondary battery includes: a positive electrode that includes a positive electrode active material layer; a negative electrode that includes a negative electrode active material layer; and a nonaqueous electrolytic solution. When a void volume of the positive electrode active material layer per battery capacity is represented by α (cm3/Ah), and when a void volume of the negative electrode active material layer per battery capacity is represented by β (cm3/Ah), the following conditions are satisfied: 1.00≦α≦2.20; (1) 2.17≦β≦3.27; and (2) α
