Title
(EN) PROCESS FOR MAKING A PARTIALLY COATED ELECTRODE ACTIVE MATERIAL
(FR) PROCÉDÉ DE FABRICATION DE MATÉRIAU ACTIF D’ÉLECTRODE PARTIELLEMENT REVÊTU
Abstract
(EN)
Process for making a partially coated electrode active material wherein said process comprises the following steps: (a) Providing an electrode active material according to general formula Li1+xTM1-xO2, wherein TM comprises Ni and, optionally, at least one transition metal selected from Co and Mn, and, optionally, at least one element selected from Al, Mg, Ba and B, transition metals other than Ni, Co, and Mn, and x is in the range of from -0.05 to 0.2, wherein at least 50 mole-% of the transition metal of TM is Ni, (b) treating said electrode active material with an aqueous formulation containing an inorganic aluminum compound dispersed or slurried in water, (c) separating off the water, (d) thermal treatment of the material obtained from step (c).
(FR)
L'invention concerne un procédé de fabrication d'un matériau actif d'électrode partiellement revêtu, ledit procédé comprenant les étapes suivantes : (a) fournir un matériau actif d'électrode selon la formule générale Li1 +xTM1 - xO2, dans laquelle TM comprend Ni et, éventuellement, au moins un métal de transition choisi parmi Co et Mn, et, éventuellement, au moins un élément choisi parmi Al, Mg, Ba et B, des métaux de transition autres que Ni, Co et Mn, et x est dans la plage de -0,05 à 0,2, au moins 50 % en moles du métal de transition de TM étant Ni, (b) traiter ledit matériau actif d'électrode avec une formulation aqueuse contenant un composé d'aluminium inorganique dispersé ou mis en suspension dans de l'eau, (c) séparer l'eau, (d) traiter thermiquement le matériau obtenu à l'étape (c).
