BATTERY AND BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2022/234815
Kind Code:
A1
Abstract:
Provided is a unit battery having a stacked unit comprising a set of a positive electrode current collector, a positive electrode active material layer, a separator, a negative electrode active material layer, and a negative electrode current collector stacked in that order, and an annular frame member arranged around the positive electrode active material layer and the negative electrode active material layer between the positive electrode current collector and the negative electrode current collector, the unit battery characterized in that a proportion of an electrode portion thickness that is the sum of the thicknesses of the positive electrode current collector, the positive electrode active material layer, the separator, the negative electrode active material layer, and the negative electrode current collector and a frame portion thickness that is the sum of the thicknesses of the positive electrode current collector, the frame member, the separator, and the negative electrode current collector (electrode portion thickness/frame portion thickness) is 1.0-5.3.
