Title:
リチウムイオン二次電池用負極体の製造方法
Document Type and Number:
Japanese Patent JP4589419
Kind Code:
B2
Abstract:
A negative electrode element for a lithium-ion secondary battery includes: a negative electrode current collector; and a negative electrode layer that includes an alloying active material layer formed on the negative electrode current collector and a resin layer formed on a surface of the alloying active material layer so as to have an opening that exposes part of the alloying active material layer to a surface of the negative electrode layer. The surface of the alloying active material layer, exposed to the opening, and a surface of the resin layer form a step so that the surface of the resin layer is farther from a surface of the negative electrode current collector than the exposed surface of the alloying active material layer.
