Process for making a coated electrode active material wherein said process comprises the following steps: (a) providing a particulate electrode active material according to general formula LiTMO, wherein TM is a combination of Ni, Co and, optionally, Mn, and, optionally, at least one metal selected from Mg, Al, Ba, Ti and Zr, and x is in the range of from zero to 0.2, wherein at least 15 mole-% of the transition metal of TM is Ni, (b) treating said electrode active material with a compound of M, wherein Mis selected from Li, Al, B, Mg, Si, Sn, and from transition metals, or a combination of at least two of the foregoing, with or without a solvent, wherein said compound of Mdoes not act as a cathode active material on its own, (c) optionally, removing compound of Mwhich is not deposited on said particulate electrode active material, (d) performing a post-treatment by heating the material obtained after the step (b) or (c), if applicable, at a temperature from 250 to 950° C. in a fluidized bed.

Process for making a coated electrode active material

The present invention is related to a process for coating anoxide material, said process comprising the following steps: (a) providing a particulate material selected from lithiated nickel-cobalt aluminum oxides, lithiated cobalt-manganese oxides and lithiated layered nickel-cobalt-manganese oxides, (b) treating said cathode active material with a metal alkoxide or metal amide or alkyl metal compound, (c) treating the material obtained in step (b) with moisture, and, optionally, repeating the sequence of steps (b) and (c), wherein steps (b) and (c) are carried out in a mixer that mechanically introduces mixing energy into the particulate material, or by way of a moving bed or fixed bed, and wherein steps (b) and (c) are carried out at a pressure that is in the range of from 5 mbar to 1 bar above normal pressure.

Process for coating an oxide material

Process for making an at least partially coated particulate material, said process comprising the following steps: (a) providing a particulate material selected from lithiated nickel-cobalt aluminum oxides and layered lithium transition metal oxides, (a) treating said cathode active material with a metal alkoxide or metal amide or alkyl metal compound in a fluidized bed, (b) treating the material obtained in step (b) with moisture in a fluidized bed, and, optionally, repeating the sequence of steps (b) and (c), wherein the superficial gas velocity in the fluidized beds in steps (b) and (c) decreases with increasing reactor height.

Process for making a lithiated transition metal oxide

Process for manufacturing a lithiated transition metal oxide, said process comprising the steps of (a) mixing at least one lithium salt and a precursor selected from transition metal oxides, transition metal oxyhydroxides, transition metal hydroxides, and transition metal carbonates, (b) pre-calcining the mixture obtained in step (a) at a temperature in the range of from 300 to 700&#xb0; C., and (c) calcining the pre-calcined mixture according to step (b) in a multi-stage fluidized bed reactor at a temperature in the range of from 550&#xb0; C. to 950&#xb0; C., wherein the temperatures in step (b) and (c) are selected in a way that step (c) is being performed at a temperature higher than that of step (b).

The invention relates to a gas distributor nozzle () comprising a gas feed () directed vertically upwards and a float () with which an outlet orifice out of the gas feed () may be closed if no gas is flowing, wherein the float () has a center of gravity which is below a point of force application of the gas flow. The invention further comprises a reactor with a solid bed and at least one gas distributor nozzle ().
