Date Dec. 12, 1991.Ceramic electrodes of cadmium germanate and other ternary oxide materials, provide electrodes for secondary battery cells. Open circuit voltages of 1.5 volts are attainable. The absence of crystallographic phase changes on charge/discharge is noted and renders possible the use of solid electrolytes, possibly in a unitary ceramic structure. |
