ABSTRACT:
This invention relates to a secondary battery comprised of three polymer films, the third containing an electrolyte and the first and second containing an electrochemical species which may be in an anodic or a cathodic state depending upon whether the battery is discharging or is being recharged. The third polymer sheet is substantially not electrically conductive under battery discharge voltages, but is electrically conductive under battery recharge voltages. The first and second sheets are electrically conductive under both the discharge and recharge voltages. In a preferred form, the electrolyte and the electrochemical species are uniformly distributed within their respective films by dissolving the electrolyte and the species in a plasticizer which is incorporated within the polymer films.
