Abstract

Vanadium oxide glasses containing transition-metal oxides M m O n were prepared by rapid quenching, and the electrochemical insertion of lithium ions into these glasses was investigated. The lithium cells with these glasses showed high open-circuit voltages (OCV) of over 3.0 V, and OCV of the cells were found to decrease with an increase in the stoichiometric parameter x=Li/(M+V). The chemical diffusion coefficients of the glass containing Fe 2O 3 were higher by 1–2 orders of magnitude than those of pure V 2O 5 glass.
