Abstract

Vanadium pentoxide (V2O5) xerogels containing some foreign metal cations, Na+, Ca2+ and La3+, have been prepared by ion-exchange of hydroxonium ions, H3O +, and investigated as a cathode material for rechargeable lithium battery. The discharge capacities of the cation-exchanged V2O 5 xerogels are identical to that of V2O5 xerogel containing H3O+ at low current density. However, the capacities of the cation-exchanged V2O5 xerogels became lower than that of V2O5 xerogel containing H 3O+ with an increase in current density, suggesting the columbic interaction between the foreign metal cations and lithium ions hinders the diffusion of lithium ions between the layers.
