Abstract:
The present invention aims to provide a binder for a power storage device electrode which is excellent in adhesiveness and capable of improving the flexibility of an electrode to be obtained when used as a binder for a power storage device electrode, and which has high resistance against electrolytes. The present invention also aims to provide a binder for a power storage device electrode which favorably maintains adhesiveness between active materials in a long-term cycle, and which enables production of a high-capacity storage battery with a small irreversible capacity and low resistance to have excellent output characteristics. The present invention further aims to provide a composition for a power storage device electrode, a power storage device electrode, and a power storage device each prepared using the binder for a power storage device electrode. The present invention relates to a binder for a power storage device electrode used for an electrode of a power storage device, the binder containing a polyvinyl acetal resin, the polyvinyl acetal resin having a hydroxy group-containing structural unit of the formula (1) comprising a hydroxy group-containing structural unit with a sequence length of 1, the hydroxy group-containing structural unit with a sequence length of 1 constituting 25% by weight or less of the whole hydroxy group-containing structural unit in the polyvinyl acetal resin, the polyvinyl acetal resin having a hydroxy group content of 30 to 60 mol %:
