METHOD FOR PRODUCING LITHIUM TRANSITION METALATES

摘要

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.
