The invention relates to a nanostructured material. Said material is a nanostructured carbon material consisting of agglomerates of small needles of Li1+aV3O8 and ßLixV2O5 (0,l<= .alpha. <= 0,25 et 0,03 <= x <= 0,667 surrounded by a discontinuous coating of spherical carbon particles. It is obtained by means of a process consisting in preparing a carbon precursor gel by bringing carbon V2O5- .alpha. an a Li precursor into contact with each other the amounts thereof being such that the ratio of concentrations V2O5/Li ranges from 1.15 to 1.5 and the mass ratio (carbon)/ (carbon + V2O5+ Li precursor) is 10 to 15 and in subjecting the gel to heat treatment including a first stage at 8O0C - …

Why it's free to use
- Filed October 18, 2005 and granted August 27, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 18, 2025.
