Document Type and Number:
WIPO Patent Application WO/2021/003680
Kind Code:
A1
Abstract:
Disclosed is a electrode sheet (10), comprising an electrode sheet main body (11), wherein the electrode sheet main body (11) comprises a coating unit (113); the coating unit (113) comprises at least one of a coating unit (113) in the shape of a regular hexagon and a coating unit (113) in the shape of a trapezoid; and the coating unit (113) in the shape of a trapezoid comprises a first oblique edge, a first parallel edge, a second oblique edge, and a second parallel edge, which are connected in sequence, with the distances from the midpoint of the second parallel edge to the four vertexes of the trapezoidal coating unit (113) being equal, and with the lengths of the first oblique edge, the first parallel edge and the second oblique edge being equal. A battery unit (100) using the above electrode sheet (10), and a battery pack (200) using the battery unit (100) are disclosed. The electrode sheet (10) improves the deformation capacity of the battery pack (200).
