The invention relates to a chemical compound of the formula NiM1M2(O)(OH), wherein M1 denotes at least one element from the group consisting of Fe, Co, Mg, Zn, Cu and/or mixtures thereof, M2 denotes at least one element from the group consisting of Mn, Al, B, Ca, Cr and/or mixtures thereof, wherein b&#x2264;0.8, c&#x2264;0.5, d&#x2264;0.5, and x is a number between 0.1 and 0.8, y is a number between 1.2 and 1.9, and x+y=2. A process for the preparation thereof, and the use thereof as a precursor for the preparation of cathode material for secondary lithium batteries are described.

Methods of making inorganic compounds

A process for producing a homogenous multi compound system which is hydroxide- and/or oxide-based includes a first alternative process comprising providing a first and a second refractory metal in respective hydrofluoric solutions, and mixing the first and second hydrofluoric solutions to provide a mixed hydrofluoric solution comprising a dissolved first and second refractory metal. A second alternative process comprises dissolving the first and the second refractory metal in an alternative mixed hydrofluoric solution. The mixed hydrofluoric solution or the alternative mixed hydrofluoric solution is precipitated with a precipitant to provide a solids mixture in a suspension. The first and second refractory metal is from the group consisting of Mo, W, Nb, Re, Zr, Hf, V, Sb, Si, Al, and Ta. The first and second refractory metal are different. At least one of the first and second refractory metal is provided as a fluoro and/or as an oxyfluoro complex.

The present invention relates to a particulate mixed metal hydroxide that includes nickel, cobalt and aluminium. The powder particles have a core of nickel/cobalt hydroxide, and a surface that is coated with amorphous aluminium hydroxide. A process for the continuous preparation of such mixed metal hydroxides is also described. The process includes precipitating aluminium hydroxide in the presence of a nickel/cobalt mixed hydroxide in a tube reactor. The mixed metal hydroxides of the present invention may be used to prepare active materials for positive electrodes of a secondary battery.
