Title (EN) METHOD FOR MODIFICATION OF A LITHIATED OXIDE COMPRISING AT LEAST ONE TRANSITION METAL POSITIVE ELECTRODE COMPRISING SAID OXIDE AND LITHIUM BATTERY
(FR) PROCEDE DE MODIFICATION D'UN OXYDE LITHIE COMPRENANT AU MOINS UN METAL DE TRANSITION, ELECTRODE POSITIVE COMPRENANT CET OXYDE ET ACCUMULATEUR AU LITHIUM
Abstract: front page image
(EN)The invention relates to a chemical modification method for a lithiated oxide comprising at least one transition metal, successively using the following steps: a step for bringing said oxide into contact with an aqueous solution containing phosphate ions, a step for separation of said oxide from the aqueous solution and a step for drying of said oxide. The invention further relates to use of the modified oxide as active material for a positive electrode of a lithium battery.
(FR)La présente invention a trait à procédé de modification chimique d'un oxyde lithié comprenant au moins un métal de transition, comprenant successivement : - une étape de mise en contact dudit oxyde avec une solution aqueuse comprenant des ions phosphate ; - une étape de séparation dudit oxyde de la solution aqueuse ; - une étape de séchage dudit oxyde. Utilisation de l'oxyde modifié de métal de transition lithié comme matériau actif d'électrode position pour accumulateur au lithium.
