Abstract
The vanadium bronze Li//1// plus //x V//3O//8 compares well with other cathodic materials for high-energy, rechargeable lithium batteries, such as TiS//2 and V//60//1//3. On the basis of this evidence, further investigations were undertaken aimed at: a) the development of 1-5 Ah Li/Li//1// plus //x V//3O//8 batteries; b) the elucidation of interfacial and bulk characteristics of the vanadium bronze electrodes. The latter task has been accomplished with the help of SEM, polarization, Li** plus diffusion and impedance data. The results are consistent with an increase in charge transfer and diffusion resistance at high degrees of intercalation. The formation of a passivation layer on the cathode surface via electrolyte decomposition and a decrease of chemical Li** plus diffusion upon intercalation, were also evidenced.
