Abstract
To provide a binder for secondary battery using non-aqueous electrolyte which is soluble in usual organic solvents, does not swell in a non-aqueous electrolyte and besides enhances battery performance. As the binder, a copolymer comprising 50 to 80% by mole of vinylidene fluoride, 17 to 50% by mole of tetrafluoroethylene and less than 3% by mole of a monomer copolymerizable therewith is used.
