Abstract
Official abstract text for this publication.
A composition for a non-aqueous secondary battery functional layer contains a binder and inorganic particles including a sulfonate group. A non-aqueous secondary battery includes a functional layer for a non-aqueous secondary battery that is formed using this composition for a non-aqueous secondary battery functional layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition for a non-aqueous secondary battery functional layer comprising: a binder; and inorganic particles including a sulfonate group, wherein the inorganic particles have a percentage content of 80 mass % or more relative to total solid content. 2. The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein the inorganic particles have a sulfonate group content of at least 0.1 μmol/g and not more than 1,200 μmol/g. 3. The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein the binder includes a sulfonate group. 4. 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 . 5. A non-aqueous secondary battery comprising the functional layer for a non-aqueous secondary battery according to claim 4 . 6. The non-aqueous secondary battery according to claim 5 , comprising a positive electrode, a negative electrode, an electrolysis solution, and a separator, wherein the separator includes the functional layer for a non-aqueous secondary battery. 7. The non-aqueous secondary battery according to claim 5 , wherein the positive electrode contains a positive electrode active material including one or more of Co, Mn, Fe, and Ni.
