The reactor is used for producing nano-particles of metal from volatile moieties in flow through mode. The reactor comprises at least a first feeder and a second feeder on one end of the vessel. The first feeder feeds the moiety in the form of an educt fluid into the reactor. This fluid is a mixture of metal moieties and a bearer fluid, entering the reactor in a vaporized state, in which the bearer fluid is used as a carrier gas. The second feeder is used as a radiator means to heat up the educt fluid within the reactor. By providing the heating fluid through the second feeder control over some environmental conditions like ambient temperature within the reactor is achieved and dissociation of the metal moieties under such controlled conditions leads to quantitative production of selected nano-particle morphologies.

The present invention relates to manganese-containing nickel(II) hydroxide powders, wherein at least 50 mole % of the manganese are present in the trivalent oxidation state, a process for the preparation of such powders and battery electrodes and batteries made therefrom.

Manganese (III)-doped nickel (II) hydroxide powders

The present invention relates to a process for the preparation of manganese(III)-containing nickel(II) hydroxide powders, more than 50 mole % of the manganese being present in the trivalent oxidation state, by co-precipitation of nickel(II) and manganese salt solutions with alkali liquors.

Process for the preparation of manganese(III)-containing nickel hydroxide

Manganese(III)-containing nickel(II) hydroxide powders produced by coprecipitation carried out by dropping an acidified metal salt solution containing Ni.sup.+2 and Mn.sup.+3 ions into a feed of constant pH value, such that manganese(III) is incorporated into the nickel(II) hydroxide lattice, thereby preventing disproportionation into separate phases and improving performance characteristics of secondary battery electrodes manufactured therefrom.
