Lithium battery storage and discharge tests. [Li/SO/sub 2/ and Li/(CF)/sub n/]
A six-year storage and discharge test of ambient-temperature lithium batteries was initiated. Lithium-sulfur dioxide cells from three manufacturers and lithium polycarbon monofluoride cells from a fourth manufacturer are included. Capacity versus rate and temperature, storage versus temperature and discharge at constant and pulsed loads are being studied. Two problems were identified which will prevent cells from operating continuously for five years. They are corrosion of the glass in the glass-to-metal seal and corrosion of the anode-to-can contact. In addition, cells exposed to high-temperature storage experienced corrosion of the aluminum-to-tantalum weld in the positive lead. 15 figures.
