摘要： 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≤ α ≤ 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- α 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 - 15O0C pendant 3-12 h, and a second stage between 3000C and 35O0C, during 10 mins to 1 hour, in a nitrogen or argon atmosphere. n. Applications: positive-electrode active material.

摘要： The invention concerns a colloidal dispersion of a vanadate or a phosphovanadate of at least a rare earth characterized in that it comprises either a complex-forming agent having a pK (cologarithm of the dissociation constant of the complex formed by the complex-forming agent and said rare earth) higher than 2.5, or an anion of a monovalent acid, soluble in water and having a pKa ranging between 2.5 and 5. In the case of a vanadate dispersion, the particles have an average size of not more than 6 nm. The inventive dispersion is obtained by a method which consists in contacting a colloidal dispersion or a dispersion of initial complexes comprising at least a rare earth compound and at least a complex-forming agent or an anion of said monovalent acid and whereof the pH has been adjusted to a value of at least 7, with vanadate ions and, if required, with phosphate ions, then in adjusting the pH of the resulting medium to a value of at least 9 and heating.
