Abstract: The invention relates to a method for producing lithium-transition metal mixtures of general formula Lix(M1yM21-y)nOnz, wherein M1 represents nickel, cobalt or manganese, M2 represents chromium, cobalt, iron, manganese, molybdenum or aluminium, and is different from M1, n is 2 if M1 represents manganese and is 1 otherwise, x is comprised between 0.9 and 1.2, y is comprised between 0.5 and 1.0 and z is comprised between 1.9 and 2.1. According to the inventive method, an intimate mixture composed of transition metal compounds containing oxygen and of a lithium compound containing oxygen is calcinated, said mixture being obtained by processing a solid powder transition metal compound with a solution of said lithium compound, and then drying. At least the M1 compound is used in powder form having a specific surface of at least 20 m2/g (BET) and calcination is carried out in a fluidised bed.

Abstract: The invention relates to a method for producing lithium transition metalates of the general formula (I): Lix(M1yM21−y)nOnz, where M1 represents lithium, cobalt or manganese; M2 represents cobalt, iron, manganese or aluminium and is not equal to M1; n is equal to 2 if M1=M, and 1 in all other cases; x is a number between 0.9 and 1.2; y is a number between 0.5 and 1.0; and z is a number between 1.9 and 2.1. According to the method, an intimate solid mixture is produced of oxygen-containing compounds of the transition metals and oxygen-containing lithium compounds and this mixture calcinated in a reactor, whereby calcination takes place at least partly at an absolute pressure of less than 0.5 bar.
