A pseudoternary system was investigated in the temperature range from 800 to 1100°C. A new compound with ramsdellite structure was discovered. The ramsdellite-type phase was obtained alone at temperatures above 1000°C in the composition range of The ramsdellite structure showed reversible extraction and insertion cycles of lithium at the potential of ca. 4.0 V vs. as well as 1.5 V. The former potential was attributed to a redox couple of and the latter to The crystal structure was maintained against the electrochemical extraction and insertion of lithium, and the cell volume was almost unchanged in the processes. © 2002 The Electrochemical Society.
