Sealed Primary Lithium-Inorganic Electrolyte Cell.

摘要

The objective of this program is to develop a D cell which is storable and operable in the temperature range of -40 to 160 F and is capable of delivering in excess of 150 WHr/lb at the thirty hour rate and peak power density of 50 watts/lb and a capacity degradation of less than 10% after one month of storage at 160 F. We showed that all the above objectives can be met by the hermetic Li/SOCl2 D cells developed by us. In fact, the low rate D cells developed by us on a separate program delivered capacities of 18 A.Hr at a constant voltage of 3.5 volt corresponding to an energy density of 290 WHr/lb and 20 WHr/cu in. at low drains (0.01-0.03A). High rate cells routinely delivered 12A.Hr at 1.0A drain corresponding to energy density of 156 WHr/lb and 11 WHr/cu in.
