Beschreibung
Zusammenfassung:	The invention relates to a process for the preparation of overlithiated transition metal oxides, for example Li2NiO2, from a mixture consisting of lithium peroxide and at least one transition metal oxide or a manganese-containing spinel compound in a two-stage calcination process with respect to temperature and atmospheric composition. L'invention concerne un procédé de préparation d'oxydes de métaux de transition surlithiés, par exemple Li2NiO2, à partir d'un mélange constitué de peroxyde de lithium et d'au moins un oxyde de métal de transition ou d'un composé de spinelle contenant du manganèse dans un procédé de calcination en deux étapes par rapport à la température et à la composition atmosphérique.
