摘要 |
A secondary battery porous membrane, manufactured by a slurry for secondary battery porous membrane, which is superior in coating priority and dispersibility of non-conductive organic particles, which improves cycle characteristic of the obtained secondary battery, which has high flexibility and can prevent powder falls, and which has less content of moisture amount; and non-conductive organic particles, which can be suitably used as a secondary battery porous membrane and has less content of metallic foreign particles. The slurry for secondary battery porous membrane comprises; a binder including a polymerized unit of vinyl monomer having a hydrophilic acid group, a non-conductive organic particle having a functional group, cross-linkable with the hydrophilic acid group and a solvent. |
