  • Publication number: 20230131265
    Abstract: The invention relates to a process for thermally treating, in particular synthesizing and/or drying and calcinating, a nano- and/or micro-scale or nano- and/or micro-crystalline battery material (BM) and/or battery material precursor (BM) in a thermal reactor (1), comprising the steps of: introducing a starting compound (AV) into the reactor (1), the starting material (AV) being a battery material (BM) and/or battery material precursor (BM) and the starting material (AV) being introduced into the reactor (1) in the form of a solution, slurry, suspension or in a solid state of matter, thermally treating the battery material (BM) and/or battery material precursor (BM) carried in a hot gas flow (HGS) in a treatment zone in the reactor (1) at a temperature of 150° C. to 1000° C., and discharging the battery material (BM) obtained from the reactor (1) in the form of a powder.

  • Patent number: 10874891
    Abstract: The invention relates to methods for producing hydrophobized, doped or non-doped mixed metal oxide nanoparticles or doped metal oxide nanoparticles by flame spray pyrolysis, wherein a combustible precursor solution A, containing at least two metal alkyloates of general formula Me(OOC—R)x with differing metals Me, or a combustible precursor solution B containing at least one metal alkyloate of general formula Me(OOC—R)x and at least one metal salt containing a metal ion Me and at least one metal salt containing a metal ion Me, with Me selected from metal ions of the subgroups of the periodic system of the elements, with R=alkyl or aryl, wherein the alkyl chain is branched or straight, and wherein x corresponds to the oxidation step of the metal ion, is used in stoichiometric excess relative to a quantity of oxygen, and wherein a combustion ratio ? of 3.5 bis 0.4 is established, and hydrophobized nanoparticles and the use thereof.
