Abstract
A method for producing cathode particles is provided. The method includes: providing a plurality of precipitation zones from i=1 to N, wherein the precipitation zones are connected in series, each precipitation zone comprises a feed stream (ai) providing the precipitation cations, a feed stream (bi) providing the precipitation anions, a continuous outflow (ci) of precipitation particle slurry to the next precipitation zone, and a continuous inflow (ci−1) of precipitation particle slurry from the prior precipitation zone, and forming, in the precipitation zones, precipitated particles, and finally to form, in the precipitation zone N, precursor particles comprised of N layers, wherein layer i of each particle is precipitated and formed in the precipitation zone i, wherein N is not less than 3, and when i=1, there is no inflow (ci−1).
