Document Type and Number:
WIPO Patent Application WO/2021/192256
Kind Code:
A1
Abstract:
In this electrode body, a first end of a cell sheet is wound around a shaft, the cell sheet having: a current collector having a first layer, a first metal layer, and a second metal layer; a first active material layer laminated on the first metal layer; a second active material layer laminated on the second metal layer; and a separator that contacts the first active material layer or the second active material layer. On a first end of the current collector, the first metal layer and the second metal layer are not laminated on at least some of the first surface and the second surface of the first layer. Alternatively, on a second end of the current collector, the first metal layer or the second metal layer is not laminated on the surface that constitutes part of the first surface and the second surface of the first layer and that lies outside of the winding body.
