BINDER COMPOSITION FOR ALL-SOLID-STATE SECONDARY BATTERY, SLURRY COMPOSITION FOR ALL-SOLID-STATE SECONDARY BATTERY ELECTRODE MIXTURE LAYER, SLURRY COMPOSITION FOR ALL-SOLID-STATE SECONDARY BATTERY SOLID ELECTROLYTE LAYER, AND ALL-SOLID-STATE SECONDARY BATTERY

摘要

The purpose of the present invention is to provide an all-solid-state secondary battery binder composition which can form a solid electrolyte-containing layer which, in an all-solid-state secondary battery, can exhibit excellent output characteristics and high-temperature cycle characteristics. This binder composition contains a polymer A; the polymer A contains nitrile group-containing monomer units and aliphatic conjugated diene monomer units; the content ratio of the nitrile group-containing monomer units in the polymer A is 5-30 mass%, the content ratio of the aliphatic conjugated diene monomer units is 40-95%, and the Mooney viscosity (ML_{1+4, 100°C) of the polymer A is greater than or equal to 65.}
