BINDER RESIN COMPOSITION FOR SECONDARY BATTERY ELECTRODES, SLURRY FOR SECONDARY BATTERY ELECTRODES, ELECTRODE FOR SECONDARY BATTERIES, AND LITHIUM ION SECONDARY BATTERY

摘要

A binder resin composition for secondary battery electrodes of the present invention contains a polymer (A) that has a structural unit represented by general formula (1) and a water-insoluble particulate polymer (B-1) and/or a water-soluble polymer (B-2). The polymer (B-2) has an acidic group and/or a salt thereof. A slurry for secondary battery electrodes of the present invention contains the binder resin composition for secondary battery electrodes of the present invention, an active material and a solvent. An electrode for secondary batteries of the present invention is provided with a collector and an electrode layer that is arranged on the collector, and the electrode layer contains an active material and the binder resin composition for secondary battery electrodes of the present invention. Alternatively, the electrode layer is obtained by applying the slurry for secondary battery electrodes of the present invention to the collector, and drying the slurry thereon. A lithium ion secondary battery of the present invention is provided with the electrode for secondary batteries of the present invention.
