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 %:

Claim (Index 8):
A composition for a power storage device electrode, comprising the binder for a power storage device electrode according to  claim 1 , and an active material,\n the composition containing the polyvinyl acetal resin in an amount of 0.1 to 12 parts by weight relative to 100 parts by weight of the active material.
