| Popis: | Vanadium oxides of various compositions were synthesized and evaluated as rechargeable cathodes in cells of the type Li/2Me-THF/LiAsF/sub 6//V-oxide, C. The most useful compositions were found to be VO/sub 2.17/, VO/sub 2.19/, and the Fe or the Cr substituted oxide of apparent composition, M/sub 0.13/V/sub 0.87/O/sub 2.17/. In high capacity cells, VO/sub 2.17/ exhibited a capacity of approximately 0.55 electrons/vanadium (e/sup -//V) at current densities of 0.5, 1, and 2 mA/cm/sup 2/ and 0.45 e/sup -//V at 4 mA/cm/sup 2/. The excellent rechargeability of this oxide in practical cells within cycling limits of 3.0 and 1.9V was demonstrated by extended cycling of a cell with an average cathode utilization of approximately 0.52 e/sup -//V in over 200 cycles. 21 refs. |
