Title:
ELECTRODE ASSEMBLY AND METHOD FOR MANUFACTURING SAME, AND BATTERY CELL, BATTERY AND ELECTRIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/082290
Kind Code:
A1
Abstract:
Provided in the present application are an electrode assembly and a method for manufacturing same, and a battery cell, a battery and an electric apparatus. The electrode assembly comprises: a first pole piece, wherein the first pole piece is coated with an active substance layer and a viscous substance layer on each of two sides in a pole piece thickness direction, and the active substance layer and the viscous substance layer on each side are arranged in parallel in a pole piece height direction; and diaphragms, which are provided on the two sides of the first pole piece in the pole piece thickness direction, and are arranged on the first pole piece in a stacked manner, wherein when the electrode assembly is in an unfolded state, the diaphragm on each side of the first pole piece has a continuous integral structure, and the diaphragms are connected to the first pole piece by means of the viscous substance layer. A first pole piece is coated with viscous substance layers, such that diaphragms are adhered to the first pole piece by means of the viscous substance layers, and thus the positions of the diaphragms and the first pole piece are fixed, without the need to coat the diaphragms with adhesive layers, thereby reducing the cost, and improving the production efficiency.
