ABSTRACT:
A slurry composition for electrode comprising a binder, an active material, and a liquid medium, characterized in that the binder comprises a polymer (X) comprising 60 to 95 mole % of repeating units derived from acrylonitrile or methacrylonitrile and 5 to 30 mole % of repeating units derived from at least one kind of a monomer selected from 1-olefins and compounds represented by the following general formula (1): CH2═CR1—COOR2wherein R1represents a hydrogen atom or a methyl group and R2represents an alkyl group; and the liquid medium is capable of dissolving the polymer (X). The slurry composition allows the manufacture of a lithium ion secondary battery having enhanced capacity and good charge-discharge cycle characteristics and good charge-discharge rate characteristics.
