Document Type and Number:
WIPO Patent Application WO/2021/175122
Kind Code:
A1
Abstract:
Disclosed are a composite polymer, and a preparation method therefor and an application thereof. The composite polymer is a block copolymer of polyfurfuryl alcohol and polyoxyethylene. The composite polymer has excellent bonding performance, electron conduction performance, and ion conduction performance, is beneficial for improving the quality and the peeling force of a pole piece, and improves the cycle performance, the rate capability, and the safety performance of a battery.
