Abstract :
Performance characteristics of AA cells based on the Li/TiS2 couple and utilizing a proprietary electrolyte are presented and discussed. These general purpose, medium power, AA cells provide 1.0 Ah, have an average discharge voltage of 2.1 V at 23°C, and a service life of 250 full depth of discharge cycles. Their energy density at the C/3 rate is 130 Wh/kg and they can be discharged up to about the C rate without significant loss of capacity. Operating temperatures extend from -20°C to ±45°C. Their safety is not compromised by electrical abuse provided cell temperatures do not exceed 140°C
