Abstract

Provided is a binder composition capable of forming a functional layer that can both inhibit post-cycling swelling of a secondary battery and increase charge carrier acceptance of the secondary battery at low temperatures. The binder composition contains a first polymer, a second polymer, and a solvent. The first polymer is a block copolymer including a block region formed of an aromatic vinyl monomer unit and a block region formed of an aliphatic conjugated diene monomer unit and/or a hydrogenated aliphatic conjugated diene monomer unit. The second polymer is a random copolymer including a 1,3-pentadiene unit and/or a hydrogenated 1,3-pentadiene unit.
