Abstract
Disclosed is a composition for non-aqueous secondary battery functional layer which comprises non-conductive particles; a water-soluble polymer having a degree of swelling in electrolyte solution of greater than 1.0 time and 2.0 times or less; and a water-insoluble polymer having a volume-average particle diameter of 0.01 μm or more and 0.30 μm or less.
Claims6
A composition for non-aqueous secondary battery functional layer, comprising:
- non-conductive particles;
- a water-soluble polymer comprising 70% by mass or more and 99% by mass or less of a (meth)acrylamide monomer unit and having a degree of swelling in electrolyte solution of greater than 1.0 time and 2.0 times or less;
- and
- a water-insoluble polymer having a volume-average particle diameter of 0.01 μm or more and 0.30 μm or less, wherein
- the volume-average particle diameter of the water-insoluble polymer is 0.15 times or more and 0.60 times or less a volume-average particle diameter of the non-conductive particles.
