Abstract

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.

Claims (14)

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.
