Title:
METHOD AND APPARATUS FOR ELECTRODEPOSITING ACTIVE MATERIAL PARTICLES ON ELECTRODE CURRENT COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2022/166996
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and apparatus for electrodepositing active material particles on an electrode current collector. The apparatus comprises an electrophoresis tank (2), wherein an electrolyte is contained in the electrophoresis tank (2), and solid particles to be deposited and the electrolyte form a sol; said solid particles are a substance or a mixture of a plurality of substances; a deposited conducting strip (5) vertically stands in the middle of the electrophoresis tank (2), and is connected to a positive electrode or a negative electrode of a direct-current power source (10), and a counter electrode (1) is divided into two parts, which are symmetrically distributed on two sides of the deposited conducting strip (5); the deposited conducting strip (5) is a flexible conducting strip or a non-flexible conducting strip; and the solid particles dispersed in the electrolyte are electrodeposited on two surfaces of the deposited conducting strip (5) by means of electrophoresis. By means of the present invention, an active material can be directly deposited on a flexible porous material, and continuous coating of a deposited conducting strip during a moving process can be realized by means of continuous electrodeposition.
