Abstract

An aniline polymer having structural Formula I: ##STR1## wherein both n1 and n2 are integers of 2 or more, m is an integer of 0 or more and X.sup.- is any anion. A substance for use in an electrode must be an aniline polymer having preferably two or more serial S--S linkages, such as "S--S--S", "S--S--S--S" and the like, consisting of sulfur. By having such structures, the substance, when used as an electrode active material, serves to improve capacity considerably as compared with other conventional electrode active materials.
