Title:
NON-AQUEOUS SECONDARY BATTERY BINDER POLYMER, NON-AQUEOUS SECONDARY BATTERY BINDER COMPOSITION, AND NON-AQUEOUS SECONDARY BATTERY ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2024/034574
Kind Code:
A1
Abstract:
This non-aqueous secondary battery binder polymer has a first structural unit derived from a monomer (a1), a second structural unit derived from a monomer (a2) and a third structural unit derived from a monomer (a3). The monomer (a1) is a non-ionic compound having only one ethylenically unsaturated bond. The monomer (a2) is a compound which has a carboxyl group and has only one ethylenically unsaturated bond. The monomer (a3) is a polyrotaxane having: cyclic molecules each having a cyclic skeleton to which a group having an ethylenically unsaturated bond is bonded; and a chain-like molecule which passes through open parts of the cyclic molecules and has a stopper group at both terminals.
