Document Type and Number:
WIPO Patent Application WO/2019/113881
Kind Code:
A1
Abstract:
Provided is a preparation method for a current collector. The method comprises the following steps: (1) anchoring a vinyl group to a fabric surface by means of a silanization reaction between a hydroxyl group of the fabric surface and a coupling agent; (2) forming a polymer brush on the fabric surface by means of in-situ free radical polymerization; and (3) forming a catalyst ion on the polymer brush by means of ion exchange, and then performing electroless plating to form a metal coating. Further provided is a current collector prepared by the above method and a lithium-ion battery containing the current collector. The current collector has high conductivity and optimal mechanical flexibility. Therefore, a lithium-ion battery containing the current collector is suitable for portable and wearable devices.
