1. Method for producing a lithium-containing oxide comprising one or more other metal elements comprising the following successive steps:
a) a step of contacting at least one coordination polymer comprising an organic part and the metal element or other metal elements bonded to one another by organic ligands with a lithium source;
b) a single step of calcination of the mixture produced from step a), whereby the suppression of the organic part of the coordination polymer and the formation of the lithium-containing oxide are obtained.
