Abstract

The negative electrode for lithium-ion secondary battery is used in which a product of tensile strength and thickness of a negative electrode having a negative electrode active material layer containing silicon and silicon oxide as main components is 3.8 to 9.0 N/mm and a value obtained by dividing the product of the tensile strength and the thickness of the negative electrode by a product of tensile strength and thickness of a negative electrode current collector is 1.06 to 1.29.
