Abstract
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.
