METHOD OF MAKING MIXED LITHIUM OXIDES SUITABLE AS ACTIVE MATERIAL FOR A POSITIVE ELECTRODE IN A LITHIUM ION BATTERY

摘要

Method of making an oxide of M, wherein M is at least one transition metal, preferably selected from Ni, Mn, or Co, or a mixture of two or more thereof, comprising at least steps (S1) and (S2): (S1) mixing a composition comprising water and at least one cation of at least one M with a composition comprising water and at least one anion selected from the group consisting of hydroxide, hydrogen carbonate, and carbonate, or a mixture of two or more thereof, in a colloid mill; (S2) precipitating an oxide or hydroxide or hydrogen carbonate or carbonate or a mixture of two or more thereof of M from the milled mixture obtained in step (S1).
