    摘要： Disclosed herein is a process for manufacturing a coated cathode active material. The process includes (a) providing a particulate electrode active material according to general formula Li1+xTM1−xO2, where TM includes Ni and optionally Co and/or Mn, optionally Al, Mg, and/or Ba, and transition metals other than Ni, Co, and Mn, and where x is between zero and 0.2, (b) treating said particulate electrode active material with an aqueous solution or slurry such that at least one element selected from Al, Sb, B, Mo, W, Si and P is deposited on the surface of said particulate electrode active material, (c) removing the water by filtration, (d) adding an aqueous solution of a compound of Al, B, or Sb to the solid residue obtained from step (c), thereby depositing Al, B, and/or Sb on the surface of said solid residue, and (e) treating the residue obtained from step (d) thermally.

    摘要： Described herein is a process for manufacturing a coated cathode active material including the steps of

    (a) providing a particulate electrode active material according to general formula Li1+xTM1−xO2, where TM is Ni,
    (b) treating said particulate electrode active material with an aqueous medium that may include a heteropoly acid or a compound of Al or Sb,
    (c) removing the water from step (b) at least partially,
    (d) optionally, adding at least one heteropoly acid or a compound of Al or Sb, as particulate compound or as aqueous solution or slurry,
    (e) optionally, treating the mixture from step (d) thermally,
    (f) adding at least one compound selected from the group consisting of B2O3, boric acid and lithium borates to the solid material obtained from step (e), if applicable, or from step (d) or (c), respectively, and
    (g) treating the residue obtained from step (f) thermally.
