✦ Synopsis

The charge and discharge behaviour of lithium cells with amorphous chromium oxide as the cathode material has been examined. Amorphous chromium oxide, a-CrsOs, with a high specific surface area was prepared by heat treating a mixture of CrsO,, water, and (NH&SO4 at 250 "C. The cells with a-Cr30s showed satisfactory discharge performance in terms of energy density. The energy density was 1800 W h kg-' at a current density of 1 mA cm-*. Cells gave good rechargeability over a wide range of charge transfer.
