A Lithium-Ion Cell Based on Li[sub 4∕3]Ti[sub 5∕3]O[sub 4] and LiVPO[sub 4]F

Abstract

The preliminary performance characteristics of a lithium-ion cell are presented. The cell delivers an average discharge voltage of and at low rates the active materials cycle at close to their theoretical utilization. At a discharge rate the cell is capable of delivering close to 80% of the rated capacity. The room-temperature stability of the insertion system was confirmed with a typical cell completing over with less than 8% discharge capacity fade. This battery chemistry may be particularly suitable for commercial applications where rate performance and safety characteristics are at a premium.
