    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.

    摘要： Process for the electrochemical decomposition of precursors in powder form by introducing a powder batch between two electrodes of an electrolysis cell, electrodes being designed to be liquid-permeable, and the electrolyte flowing through the powder batch perpendicularly to the electrode surfaces, and electrolysis cell suitable therefor, which is essentially characterized in that at least one electrode has a structure which consists of a supporting pierced plate (5), an electrode plate (3) provided with perforations, and a filter cloth (4) arranged between the supporting pierced plate (5) and the electrode plate (3), and in that the cathode (6) is shielded from the cell by means of a liquid-permeable separator (7).
