Properties of Polypyrrole‐Electrolyte‐Polypyrrole Cells

Abstract
The charging and discharging characteristics of polypyrrole‐electrolyte‐polypyrrole cells were studied. It was found that “secondary” batteries could be formed in this way with rather large coulombic efficiencies but poor charge retention properties. The coulombic capacity varied strongly with the total charge used during the production of the polypyrrole films, probably due to the morphology of the films.
