摘要： The invention relates to a method for producing metal hydroxides or alkaline metal carbonates by anode dissolution of the corresponding metals and precipitation of the hydroxides or alkaline carbonates in an aqueous medium. The anode dissolution of the metal components is carried out in the anode compartment of a three-compartment electrolytic cell. An aqueous auxiliary salt solution is fed to an intermediate compartment that is disposed between the anode compartment and the cathode compartment and that is separated therefrom by a porous membrane. An at least not alkaline metal salt solution is continuously taken from the anode compartment while an alkaline auxiliary salt solution is continuously taken from the cathode compartment. The at least not alkaline metal salt solution and the alkaline auxiliary salt solution are combined outside the electrolytic cell for the purpose of precipitating metal hydroxides or alkaline metal carbonates.

摘要： The invention relates to a device and a method for the production of compounds by precipitation of solids from solutions, the physical and chemical properties of the solid particles formed on precipitation being flexible and can be independently fixable. Custom products can thus be produced with very high space-time yields and a particulate nickel/cobalt mixed hydroxide of formula NixCo1-x(OH)2, with a BET surface area of 20 m2/g and a tap density of greater than 2.4 g/cm3.

摘要： 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.
