Abstract: The invention relates to a lithium vanadium oxide which corresponds to the formula Li1+?V3O8 (0.1???0.25). It is composed of agglomerates of small needles having a length l from 400 to 1000 nm, a width w such that 10<l/w<100 and a thickness t such that 10<l/t<100. It is obtained by a process consisting in preparing a precursor gel by bringing ?-V2O5 and a Li precursor into contact in amounts such that the ratio of the concentrations [V2O5]/[Li] is between 1.15 and 1.5 and in subjecting the gel to a heat treatment comprising a first stage at 80° C.-150° C. for 3 h to 15 days and a second stage between 250° C. and 350° C. for 4 min to 1 hour, under a nitrogen or argon atmosphere. It is useful as an active material of a positive electrode.
