| abstract |
A porous membrane slurry for secondary batteries including non-conductive particles, a porous membrane polymer, and an organic solvent, wherein the non-conductive particles are particles of a polymer that contains 50% by weight or more of a structural unit formed by polymerization of a (meth)acrylate, the polymer having a softening starting point or decomposition point of 175° C. or higher, and wherein the porous membrane polymer is in a non-particulate form and has a cross-linkable group. A secondary battery negative electrode, and a method for producing a secondary battery negative electrode, are also provided. |
