An electrode mixture layer composition for a nonaqueous electrolyte secondary battery contains an active material, water and a binder. The binder contains a crosslinked polymer of a monomer component including an ethylenically unsaturated carboxylic acid monomer, and a salt thereof. The crosslinked polymer is a polymer that is crosslinked with allyl methacrylate, and an amount of the allyl methacrylate used is 0.1 to 2.0 parts by weight relative to total 100 parts by weight of non-crosslinking monomers, and a content of the crosslinked polymer and salt thereof is 0.5% to 5.0% by weight of the active material.

Electrode mixture layer composition for nonaqueous electrolyte secondary battery, manufacturing method thereof and use therefor

The present invention relates to a method for producing porous ceramic, the method including molding a mixture containing a water absorbent polymer particle, a ceramic raw material, and water, the water absorbent polymer particle having a water absorption amount in a range of 5 to 30 ml/g at a pressure of 980 Pa, and heating and baking the resulting molded product. The water absorbent polymer particle is preferably composed of a polymer having a 2-acrylamide-2-methylpropanesulfonic acid unit or an acrylamide unit as a constituting monomer unit.
