Document Type and Number:
WIPO Patent Application WO/2024/087896
Kind Code:
A1
Abstract:
A battery adhesive, a preparation method therefor, and a lithium-ion battery. The battery adhesive comprises the following components in parts by weight: 70-90 parts of a first component and 10-30 parts of a second component; wherein the preparation raw materials of the first component comprise isocyanate, a first monomer, and a second monomer; the first monomer is selected from an aromatic dihydric phenol and/or an aromatic diamine; the second monomer is a reactive long carbon chain polymer; and the second component is an acrylonitrile copolymer. The battery adhesive has a relatively low swelling rate and relatively strong bonding capabilities in an electrolyte, resulting in better electrical performance in a prepared lithium ion battery.
