โœฆ Synopsis

The electrochemical behaviour of amorphous vanadium oxides (a-V,Os and a-VzO,--P,O,) cathodes in lithium cells has been investigated. The reversibility of the cathodes is superior to that of c-V,05 and the cathodes can operate for >300 cycles. The relationship between cathode composition and cycle performance has been determined, and P205, as a network-former, has been found not to harm the reversibility of cathodes. The degradation in capacity with cycling of the Li/a-V205(-PZ05) system is due to deterioration of the anode, i.e., an increased polarization on discharge.
