Document Type and Number:
WIPO Patent Application WO/2020/075352
Kind Code:
A1
Abstract:
A lithium ion secondary cell 100 comprises: a battery unit 1 obtained by layering, on a substrate 10 that has electroconductivity and also serves as a positive electrode collector layer, a base layer 20, a positive electrode layer 30, a solid electrolyte layer 40, a holding layer 50, a diffusion prevention layer 60, and a negative electrode collector layer 70; and a coating part 2 that has insulating properties and coats the side part of the battery unit 1. The coating part 2 is configured so as not to cover the center part of the top surface of the negative electrode collector layer 70 positioned on the upper side of the battery unit 1, or the rear surface of the substrate 10 positioned on the lower side of the battery unit 1, and these sections are used for electrical connection with the outside.
