An electrical storage device electrode binder composition containing a polymer (A) and a liquid medium (B). A repeating unit (A4) derived from an unsaturated carboxylic acid compound is included in the polymer (A) in an amount of 5-40 parts by mass based on 100 parts by mass of the total repeating units in polymer (A). The polymer (A) is in particle form, and the polymer particles have a surface acid content of 1-6 mmol/g.

Binder composition for electrical storage device electrodes, slurry for electrical storage device electrodes, electrical storage device electrode, and electrical storage device

An electrode binder composition is used to produce an electrode used for an electrical storage device, and includes (A) a polymer, (B) a compound represented by the following general formula (1), and (C) a liquid medium, the polymer (A) being fluorine-containing polymer particles or diene polymer particles, and a concentration of the compound (B) in the electrode binder composition being 5 to 500 ppm. wherein Rand Rindependently represent a hydrogen atom, a halogen atom, or a monovalent alkyl group, and n is an integer from 0 to 5.
