Abstract

A non-aqueous electrolyte secondary battery includes a power generating element having a positive electrode having a positive electrode active material layer containing lithium-nickel-manganese-cobalt composite oxide on a surface of a current collector, an electrolyte layer, and a negative electrode. At least one of the following conditions (1) to (4) is satisfied. (1) A value obtained by dividing a direct current resistance of the battery by a heat resistance in a plane direction of the battery is 0.055 or more; (2) a value obtained by dividing a direct current resistance of the battery by a heat capacity of the battery is 3.080×10or more; (3) a value obtained by dividing a battery capacity by a heat resistance in a plane direction of the battery is 880 or more; and (4) a value obtained by dividing a battery capacity by a heat capacity of the battery is 0.05000 or more.
