RESEARCH INVESTIGATIONS LEADING TO THE DEVELOPMENT AND EVALUATION OF A CADMIUM - SILVER OXIDE BATTERY HAVING A HERMETICALLY SEALED CONSTRUCTION
EAGLE-PICHER CO JOPLIN MO
Development was continued on a hermetically sealed, readily reproduced, rechargeable cadmium - silver oxide battery having a high level of reliability and performance. An excess of 400 c was obtained on the standard control cells utilizing 25 of the cells capacity during each discharge. Several types of film separators have become available, and testing of these separators was initiated. Cells were fabricated which will accept an overcharge at the 5-hour rate. Overcharge at higher rates is somewhat limited by the dissipation rate of the heat given off during the combination of oxygen and cadmium. Open circuit stand tests give an indication of the discharge characteristics of the control cells. Only limited results were obtained from the open circuit stand tests at various temperatures. Author
