Electrode for all solid-state secondary battery and method for producing same

摘要

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, includes 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, the 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.
