A dissolution-reprecipitation process from a mixed solution of NH4VO3and In(NO3)3is described for the low-temperature preparation of amorphous InVO4·2.3H2O. Crystallized phases were obtained depending on the annealing temperature of amorphous InVO4·2.3H2O. An electrochemical investigation has shown that these compounds, depending on their amorphous/crystallized nature, can react with large amounts of Li, leading to reversible capacities as large as 900 mA-h/g. Both electrochemical and in-situ X-ray diffraction studies suggest that a mechanism of Li uptake/removal, different from the usual Li insertion/deinsertion process, is occurring in these vanadates.
