Normal pressure thermal decomposition of CrOs containing cu. 2.5 wt.% SO3 yields a new chromium oxide phase CrO,(SO)s, x being close to 2.5. This material is different from Cr,Os and is practically free from sulfur. Sulphur trioxide obviously acts as a catalyst for oxygen removal. Compared with CrsO

β¦ Synopsis
The performances of organic electrolyte lithium cells with the chromium oxides, CrZ03, CrOz, Cr,Ola, CrZ05, Cr6015, and CrsOs, as cathodes, have been examined. The discharge behaviors of the couples Li/CrzOs, Li/Cr601s, and Li/Cr,O,, gave satisfactory results, especially in terms of energy density. The highest calculated energy density, based on the weights of the chromium oxides and to a 2.0 V cutoff at 0.5 mA/cm*, was 1210 W h/kg for the Li/CrsOs couple. Further, the performance of a coin-type cell with a CrsOs cathode was demonstrated, and it was found that the cell exhibited good rechargeability.
