Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A negative electrode for lithium-ion secondary battery, comprising: a negative electrode current collector having a tensile strength and a thickness, the tensile strength of the negative electrode current collector being 237 N/mm 2 or more and 441 N/mm 2 or less; and a negative electrode active material layer formed on the negative electrode current collector, the negative electrode having a tensile strength and a thickness; the negative electrode ac…
