Abstract
Official abstract text for this publication.
A composition for a non-aqueous secondary battery functional layer comprises: non-conductive particles; a water-soluble polymer containing a (meth)acrylamide monomer unit in a proportion of 70.0 mass % or more and 99.0 mass % or less; and a water-insoluble polymer containing an ethylenically unsaturated carboxylic acid monomer unit in a proportion of 1.5 mass % or more and 5.0 mass % or less and having a degree of swelling in electrolyte solution of more than 1.0 time and 3.0 times or less.

1 . A composition for a non-aqueous secondary battery functional layer, comprising: non-conductive particles; a water-soluble polymer containing a (meth)acrylamide monomer unit in a proportion of 70.0 mass % or more and 99.0 mass % or less; and a water-insoluble polymer containing an ethylenically unsaturated carboxylic acid monomer unit in a proportion of 1.5 mass % or more and 5.0 mass % or less and having a degree of swelling in electrolyte solution of more than 1.0 time and 3.0 times or less. 2 . The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein the water-soluble polymer contains a cross-linkable monomer unit in a proportion of 0.01 mass % or more and 4.0 mass % or less. 3 . The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein the water-insoluble polymer contains a cross-linkable monomer unit in a proportion of 0.01 mass % or more and 4.0 mass % or less. 4 . The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein the water-soluble polymer has a degree of swelling in electrolyte solution of more than 1.0 time and 2.0 times or less. 5 . The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein the water-insoluble polymer contains an aromatic monovinyl monomer unit in a proportion of 10 mass % or more and 60 mass % or less. 6 . The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein a content by mass of the water-insoluble polymer is 0.1 times or more and 2.5 times or less the water-soluble polymer. 7 . A functional layer for a non-aqueous secondary battery formed using the composition for a non-aqueous secondary battery functional layer according to claim 1 . 8 . A non-aqueous secondary battery comprising the functional layer for a non-aqueous secondary battery according to claim 7 .
