Document Type and Number:
WIPO Patent Application WO/2023/088052
Kind Code:
A1
Abstract:
The present application relates to the technical field of new energy, and in particular to an electrode assembly, a winding method, a device, a battery cell, a battery, and an electrical apparatus. The electrode assembly comprises a first diaphragm, a first pole piece and a second diaphragm, which are arranged in a stacked manner, wherein the first pole piece is sandwiched between the first diaphragm and the second diaphragm; and in the width direction of the first pole piece, part of edges on two sides of starting sections of the first diaphragm and the second diaphragm are fixedly connected to each other. In this way, by means of the present application, the problem of a poor alignment degree of a starting section during the winding of a pole piece in an electrode assembly can be solved.
