HIGH PERFORMANCE LITHIUM/IRON DISULFIDE CELLS

Two compact Li-Si alloy/FeS2 cells are described and their performance is discussed in terms of the requirements for electric vehicle propulsion. The highest specific energy achieved was 182.7 W.h/kg obtained at an average specific power of 9.35 W/kg. At higher specific power levels, relatively high internal resistance, combined with decreased utilization of the active material in the positive electrode, reduced the specific energy (e.g. 75.3 W.h/kg at 96.4 W/kg). Both cells achieved more than 250 deep-discharge cycles over 5000 hours of operation.
