Abstract

The vanadium bronze Li1+x V3O8 compares well with other cathodic materials for high-energy, rechargeable lithium batteries, such as TiS2 and V6O13. On the basis of this evidence, further investigations were undertaken aimed at: a) the development of 1-5 Ah Li1+x V3O8 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+ 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+ diffusion upon intercalation, were also evidenced.
