Abstract
Official abstract text for this publication.
Provided is a composition for a non-aqueous secondary battery functional layer that inhibits cissing in thin film application and enables formation of a functional layer that does not excessively increase the amount of metal deposited on an electrode during secondary battery charging. The composition for a functional layer contains organic particles, a binder, a wetting agent, and water. Content of the wetting agent is more than 1 part by mass and not more than 5 parts by mass per 100 parts by mass of the organic particles.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition for a non-aqueous secondary battery functional layer comprising organic particles, a binder, a wetting agent, and water, wherein content of the wetting agent is more than 1 part by mass and not more than 5 parts by mass per 100 parts by mass of the organic particles, the glass-transition temperature of a polymer forming the organic particles is 50° C. or higher, and the glass-transition temperature of a polymer forming the binder is lower than 50° C., the wetting agent includes a non-ionic surfactant, the wetting agent further includes a sulfosuccinic acid ester or salt thereof, and a mass ratio of content of the sulfosuccinic acid ester or salt thereof relative to content of the non-ionic surfactant is not less than 0.50 and not more than 1.30. 2. The composition for a non-aqueous secondary battery functional layer according to claim 1 , wherein a mass ratio of content of the wetting agent relative to content of the binder is not less than 0.01 and not more than 0.50. 3. 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 . 4. A non-aqueous secondary battery comprising the functional layer for a non-aqueous secondary battery according to claim 3 .
