An object of the present invention is to provide a binder which exhibits excellent dispersibility of a conductive assistant; a slurry composition and an electrode, each of which uses this binder; and an electricity storage device which is provided with this electrode.
The present invention relates to a binder for an electricity storage device, in which a loss tangent tanδ in a linear region of an aqueous dispersion liquid of 0.5% by mass of the binder and 4.6% by mass of a conductive assistant satisfies tanδ > 1 in a strain dispersion measurement under measurement conditions of a measurement temperature of 25°C and a frequency of 1 Hz, and the conductive assistant is an acetylene black having an average particle diameter of 30 nm or more and 40 nm or less and a specific surface area of 65 m2/g or more and 70 m2/g or less; a slurry composition and an electrode, each of which uses this binder; an electricity storage device which is provided with this electrode; and the like.

the design of self-assembling functional liquidcrystals as segmented or "Janus" liquid-crystalline supermolecular materials in the form of structures that contain two different types of mesogenic units, which favour different types of mesophase structure, grafted onto the same star-shaped scaffold to create supermolecules that contain different hemispheres. The materials exhibit chiral nematic and
