NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

A nonaqueous electrolyte secondary battery (100) includes: a positive electrode (10) that includes a positive electrode active material layer; a negative electrode (20) 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) 1.00≤α≤2.20; (2) 2.17≤β≤3.27; and (3) α<β.
