摘要： Slurry for secondary batteries used for manufacturing a porous membrane superior in a thermal shrinkage resistance. Said slurry for secondary batteries comprises non-conductive particles and a water-soluble polymer, wherein the water-soluble polymer is a maleimide-maleic acid copolymer including a structural unit (a) shown by the below general formula (I) and a structural unit (b) shown by the below general formula (II);

in which "R 1 " is hydrogen or a substitution group selected from the group consisting of an alkyl group having a carbon number of 1 to 6, a cycloalkyl group having a carbon number of 3 to 12, a phenyl group and a hydroxyphenyl group, and
"X" is a residual group of maleic acid which may be neutralized with an ion other than hydrogen ion, dehydrated or esterified.

摘要： To provide a secondary battery porous membrane that has superior heat resistance and flexibility and contributes to improvements in battery cycle characteristics. Also provided is a secondary battery having high cycle characteristics that uses this porous membrane. [Solution] This secondary battery porous membrane contains nonconductive particles and a binder. The binder is characterized by being formed from a polymer containing a nitrile group, a novel group, and a C 4+ straight-chain alkylene structural unit in the same molecule and the nitrile group content in the polymer constituting the binder being 1 - 25% by mass, with the iodine value of the polymer being 0 mg/100 mg - 30 mg/100 mg.
