摘要

[PROBLEMS] A secondary battery produced by using a secondary battery porous film slurry excellent in coatability and dispersibility of insulating inorganic particles, can improve the cycle characteristics of the obtained secondary battery, has high flexibility, can prevent powder from falling off, A secondary battery porous film having a reduced moisture content. [MEANS FOR SOLVING PROBLEMS] The secondary battery porous film slurry according to the present invention is characterized by comprising an insulating inorganic particle having a surface functional group selected from the group consisting of an amino group, an epoxy group, a mercapto group and an isocyanate group, and a reactive group having a reactive group capable of crosslinking with the surface functional group A binder, and a solvent.
