Rechargeable proton conducting polymeric solid-state batteries have been fabricated with the configuration Zn + ZnSO4 center dot 7H(2)O parallel to PEO:NH4ClO4 +PC parallel to V2O5 + PbO2 + C + E. The maximum cell voltage is similar to 1.57V at full charge. The discharge characteristics of the cell have been studied at different loads. The cell remains stable for more than 180 h for low current drain (similar to mu A) making it suitable for low current density application. The cell also showed a good rechargeability which was tested for nine cycles. (c) 2006 Published by Elsevier B.V.
