Abstract

Provided is a binder composition for a secondary battery electrode that has excellent binding capacity and can cause a secondary battery to display excellent rate characteristics and cycle characteristics. The binder composition for a secondary battery electrode contains: a first particulate polymer having a degree of swelling in electrolysis solution of at least 400 mass % and no greater than 900 mass % and a glass transition temperature of at least −60° C. and no higher than −15° C.; a second particulate polymer having a degree of swelling in electrolysis solution of greater than 100 mass % and no greater than 200 mass % and a glass transition temperature of at least −10° C. and no higher than 30° C.; and water.
