摘要

It is excellent in the dispersion stability of an electrode active material and a electrically conductive material, and providing the composition containing the dispersion stabilizer for electrode coating liquids of the electrical storage device which can produce uniform electrode even if the dispersion apparatus of weak shearing force is used. The dispersing agent for electrode coating liquid of an electrical storage device containing the cellulose fiber which satisfy | fills following (a)-(c). (a) Number average width of the short width side is 2-200 nm (b) Aspect ratio is 7.5 or more and 250 or less (c) has cellulose I-form crystals, the crystallinity of which is 70% or more and 95% or less
