High-energy-density rechargeable battery. Phase 2. (Lithium-metal sulfide development). Final report, Mar 1982-February 1984
This investigation of high-energy-density rechargeable batteries attempts to advance the development of high-temperature electrochemical systems and assess their suitability for military satellite missions in geosynchronous and mid-altitude orbits. A 5-plate, monopolar, lithium alloy, iron monosulfide cell used in EV's was first considered. These cells performed far below the goal of 100 Wh/kg and were therefore modified to a 7-plate, 100 Ah, lithium-aluminum-silicon alloy negative electrode, iron monosulfide positive electrode, magnesium powder separator, and ternary lithium halide electrolyte. After optimization of level I cells, two approaches were employed for subsequent cell designs. One was a stable iron disulfide positive electrode developed for incorporation into a monopolar cell. The other was the development of a bipolar-cell design. Results of a lithium iron sulfide test showed a 100 Wh/kg, one-hour discharge cell is not possible. However, cycle life was increased to 1500, and performance did not degrade after the freeze-thaw routine. The Li-AL-Si alloy negative electrode is less prone to capacity loss with cycling when operated at high current densities than a Li-AL electrode. Above 350 C the iron disulfide electrode showed rapid upper-plateau capacity decline rate. Overall performance achieved was inadequate for a main power source in geosynchronous and mid-altitude orbiting military satellites.
