ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND AUTOMOBILE, POWER TOOL OR STATIONARY DEVICE EQUIPPED WITH SAME

摘要

In a non-aqueous electrolyte secondary battery, a positive electrode in which a positive electrode active material includes a lithium-containing composite oxide, a peak pore size in a positive electrode material mixture layer is 0.7 µm or less and a pore volume per unit weight of the positive electrode active material in the positive electrode material mixture layer is 0.05 cm 3 /g or more and 0.3 cm 3 /g or less; or a negative electrode in which a negative electrode active material includes a carbon material, a peak pore size in a negative electrode material mixture layer is 0.7 µm or less, and a pore volume per unit weight of the negative electrode active material in the negative electrode material mixture layer is 0.2 cm 3 /g or more and 0.4 cm 3 /g or less are used.
