The electrochemical behaviour of amorphous vanadium oxides (a-V2O5 and a-V2O5-P2O5) cathodes in lithium cells has been investigated. The reversibility of the cathodes is superior to that Of c-V2O5 and the cathodes can operate for > 300 cycles. The relationship between cathode composition and cycle performance has been determined, and P2O5, as a network-former, has been found not to harm the reversibility of cathodes. The degradation in capacity with cycling of the Li/a-V2O5(-P2O5) system is due to deterioration of the anode, i.e., an increased polarization on discharge.
