The invention concerns a method for making transition metal oxide containing lithium or extra lithium comprising the three following steps performed successively or simultaneously: Preparing a lithium alkoxide solution by dissolving metal lithium in corresponding alcohol, said alcohol being selected among alcohols derived from linear or branched alkanes containing at least 3 carbon atoms, the alcohols derived from unsaturated aliphatic hydrocarbons, and their mixtures; adding a transition metal oxide powder to said lithium alkoxide solution to obtain a dispersion; controlled reduction of said transition metal oxide by said lithium alkoxide until a transition metal oxide containing lithium or extra lithium is obtained having a specific stoichiometry Li:Metal; Said method further consists in the following steps: evaporating the residual alcohol; washing the resulting powder; drying the powder.
La présente invention a trait à un procédé de fabrication d'oxyde de métal de transition lithié ou surlithié comprenant les trois étapes suivantes, réalisées successivement ou de manière simultanée: préparation d'une solution d'alkoxyde de lithium par dissolution de lithium métallique dans l'alcool correspondant, ledit alcool étant choisi parmi les alcools issus des alcanes linéaires ou ramifiés comprenant au moins 3 atomes de carbone, les alcools issus des hydrocarbures aliphatiques insaturés, et leurs mélanges; addition d'une poudre d'oxyde de métal de transition à ladite solution d'alkoxyde de lithium pour obtenir une dispersion; réduction ménagée dudit oxyde de métal de transition par ledit alkoxyde de lithium jusqu'à obtention d'un oxyde de métal de transition lithié ou surlithié présentant une stoechiométrie définie Li : Métal; ledit procédé comprenant ensuite, en outre, les étapes suivantes: évaporation de l'alcool résiduel; rinçage de la poudre ainsi obtenue; séchage de la poudre.
