Abstract
This disclosure provides a method for preparing a current collector. The method includes: (1) anchoring vinyl groups onto the surface of textiles through the silanization between hydroxyl groups and coupling agents; (2) synthesizing polyelectrolyte brushes through in-situ radical polymerization; and (3) obtaining catalyst ions on the polyelectrolyte brushes through ion-exchange and obtaining metal-coated layers through subsequent electroless deposition). The current collector according to the present disclosure has high electrical conductivity and excellent mechanical flexibility, and thus the lithium ion battery including the same is suitable for portable and wearable electronic devices.
Claims13
A method for preparing a current collector, comprising:
- (1) anchoring vinyl groups onto the surface of a textile through the silanization of the hydroxyl groups on the surface of the textile with a coupling agent, wherein the coupling agent is γ-methacryloxypropyltrimethoxysilane;
- (2) synthesizing polyelectrolyte brushes on the surface of the textile through in-situ radical polymerization;
- (3) forming catalyst ions on the polyelectrolyte brushes through ion-exchange and forming a metal-coated layer through subsequent electroless deposition.
