Electrochemical data are reported for oxygen reduction on platinized coconut-shell charcoal electrodes in 2.5M H\*SO,, and 7M HsF'04. In both these media the electrodes exhibit good activity and can sustain currents up to 600 mA cm-\* at a polarization of about 400 mV from their rest potentials. The

In principle, vanadium pentoxide can be used as an active material for positive electrodes in rechargeable lithium cells. Cyclability is possible when the discharge is limited to a value of y = 2.35 (in Li,V,O,). The cycling behaviour is comparatively good up to a discharge level of y = 1.
