Title:
BINDER FOR POWER STORAGE DEVICE ELECTRODE
Document Type and Number:
Japanese Patent JP2017183241
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide: a binder for a power storage device electrode, which is superior in active material dispersibility, defoamability and adhesiveness, which is high in endurance against an electrolyte solution, and which enables the manufacturing a high-capacity lithium secondary battery even with a small addition amount of a binder; and a composition for a power storage device electrode, a power storage device electrode, and a power storage device which are each arranged by use of the binder for a power storage device electrode.SOLUTION: A binder for a power storage device electrode is a binder to be used for an electrode of a power storage device. The binder comprises a polyvinyl acetal-based resin fluid dispersion including microparticles made of a polyvinyl acetal based resin of which the amount of hydroxyl groups is 30-60 mol%, a nonionic surfactant and an aqueous medium.SELECTED DRAWING: None
