A high capacity aluminum-silver oxide battery

The science and development of polymer bonded electrodes is reviewed with particular reference to metal oxide cathodes. Such electrodes, based on polytetrafluoroethylene, have been prepared from silver oxide and these have demonstrated that at least 700 Wh/dm should be obtainable from the aluminum-silver oxide power source systems. The silver oxide electrodes were of 12 mm thickness, were fabricated as bipolar electrodes with aluminum anodes, and achieved capacities of 1.2 Ah/cm³ at near 100% coulombic efficiency. Scanning electron microscopy carried out on these electrodes has shown that the structure is well cemented by PTFE. The electrodes remained porous throughout discharge with good electrolyte penetration properties
