Title:
非水電解質二次電池用負極、非水電解質二次電池及び非水電解質二次電池用負極の製造方法
Document Type and Number:
Japanese Patent JP7029676
Kind Code:
B2
Abstract:
A method for producing a negative electrode for a nonaqueous electrolyte secondary battery, and a nonaqueous electrolyte secondary battery obtained therewith are disclosed. The negative electrode includes a negative electrode current collector, a negative electrode active material layer provided on the surface of the negative electrode current collector, and a first film which has lithium ion permeability and which coats at least a portion of the surface of the negative electrode active material layer and partially coats the surface of the negative electrode current collector. The first film preferably contains a first lithium compound containing an element M1, an element A1, and lithium. Herein, M1 is at least one selected from the group consisting of P, Si, B, V, Nb, W, Ti, Zr, Al, Ba, La, and Ta; and A1 is at least one selected from the group consisting of F, S, O, N, and Br.
