摘要

The present invention is directed to the provision of a binder composition for all solid state secondary batteries capable of forming a solid electrolyte containing layer capable of preparing a slurry composition for a solid electrolyte containing layer having good leveling ability and capable of exhibiting excellent output characteristics for all solid state rechargeable batteries.The binder composition of the present invention is a binder composition for all solid state secondary batteries comprising a first polymer, a second polymer, and a solvent, wherein the first polymer is poorly soluble relative to the solvent and the second polymer contains a nitrile group containing monomer unit This solvent is easily soluble.
