Abstract:
[Problem] To provide an electrode for all-solid-state secondary batteries, which is capable of improving the high-temperature cycle characteristics of an all-solid-state secondary battery. [Solution] An electrode for all-solid-state secondary batteries of the present invention comprises a collector, a conductive adhesive layer and an electrode mixture layer. The electrode mixture layer contains a binder, an inorganic solid electrolyte that contains sulfur atoms, and an electrode active material. The conductive adhesive layer contains conductive particles and a binder for adhesive layers, said binder being composed of a diene polymer. The diene polymer contains 10-75% by mass of a diene monomer unit, and has an iodine number of 5-350 mg/100 mg. The sulfur atoms contained in the inorganic solid electrolyte and carbon-carbon double bonds of the diene polymer are crosslinked with each other.
Abstract:
The present invention is characterized by containing an electroconductive carbon, a water-soluble polymer, a particulate binding agent, and a dispersion medium, in which the water-soluble polymer is an isobutylene-maleic anhydride copolymer containing a structural unit (a) represented by the following general formula (I), and is partially hydrolyzed.
Abstract:
Provided is a binder composition for an all-solid-state secondary battery with which it is possible to form a solid electrolyte-containing layer that can cause an all-solid-state secondary battery to display excellent high-temperature cycle characteristics. The binder composition for an all-solid-state secondary battery contains an acrylic polymer and not less than 500 mass ppm and not more than 20,000 mass ppm of a phosphoric acid ester emulsifier relative to the acrylic polymer.
