Rechargeable Lithium/Chromium Oxide Cells

Abstract
The charge and discharge behaviors of organic electrolyte lithium cells with chromium oxides, , , and amorphous chromium oxide as the cathodes have been examined, where was obtained by heat‐treating the mixture of and water. The lithium cells with these chromium oxides gave satisfactory discharge performances in term of energy density. The cycling characteristics of the cells have been examined for various ranges of charge transferred in the chromium oxide electrode, such as 0.1–0.3, 0.4–0.6, and 0.7–0.9 e /Cr. The cells showed a poor cycling performance for the whole range of charge transferred. The rechargeability of the cells was good, in the range 0.4–0.6 and 0.7–0.9 e /Cr, but poor in the range 0.1–0.3 e /Cr. The cells worked well as a rechargeable cell for the whole range of charge transferred.
