Abstract (en)
[origin: WO2018015210A1] A metal carbonate material comprising nickel and manganese in an atomic ratio of 0 ≤ Ni:Mn ≤ 1/3 is produced by a method for precipitation synthesis, where seed particles are produced continuously, agglomerated and grown in a first reactor, a specific amount of the product suspension is transferred batch-wise or continuously to a stirred second reactor, and a further continuous feed of raw materials in a fixed ratio is added to this second reactor to grow the particles. This step is optionally repeated one or more times, and then the final product is collected batch-wise or continuously from the last reactor.
