Lithium insertion behaviours of Li1+xV3O8 and its modified oxides were examined. Li4V3O8 phase was formed at x = 1.5 in Li1+xV3O8 and had smaller insertion rate of lithium. Modification of VO5 unit in the layer and neighboring octahedral Li+ ions in the interlayer affected the formation of Li4V3O8 phase. Lattice disorder and layer stacking of the mother oxide also influenced the insertion behavior of Li4V3O8 phase.
