  • Method for the precipitation of particles of a metal carbonate material without use of a chelating agent
    Patent number: 11952287
    Abstract: In a method for the precipitation of particles of a metal carbonate material comprising nickel and manganese in an atomic ratio of 0?Ni:Mn?1:3, aqueous solutions comprising sulfates or nitrates of nickel and manganese are mixed with aqueous solutions of carbonates or mixtures of carbonates and hydroxides of sodium or potassium in a stirred reactor at pH>7.5 without the use of a chelating agent. Thereby agglomerated particles are formed without any subsequent process steps, in particular no subsequent process at temperatures higher than the precipitation temperature.
    Type: Grant

  • Cathode Active Material For High Voltage Secondary Battery
    Publication number: 20190173084
    Abstract: The invention relates to a cathode active material for a high voltage secondary battery with a cathode arranged for being fully or mainly operated above 4.4 V vs. Li/Li+, wherein the cathode active material is an oxide that comprises sulfate as a capacity fade reducing compound. The invention also relates to a cathode active material for a high voltage secondary battery having the composition LixMyMn2?yO4?v(SO4)z, where 0.9?x?1.1, 0.4?y?0.5, 0<z?0.1, 0?v?z and M is a transition metal chosen from the group consisting of Ni, Mg, Ti, V, Cr, Fe, Co, Cu, Zn, Al, Ga, Rb, Ge, Mo, Nb, Zr, Si and combinations thereof, wherein the cathode active material comprises sulfate as a capacity fade reducing compound. Furthermore, the invention relates to a secondary battery comprising the cathode active material according to the invention, and to a method for preparing the cathode active materials of the invention.
