A Positive Electrode Material For Rechargeable Lithium Ion Batteries And Methods Of Making Thereof
Abstract: A method for preparing a N(M)C-based positive electrode materials according to the present invention comprises the following steps: - Precipitation of a metal (at least Ni- and Co-, preferably comprising Mn-) bearing precursor (MBP), - Fractionation of the MBP in a first (A) fraction and at least one second (B) fraction, - Lithiation of each of the first and second fraction, wherein the A fraction is converted into a first polycrystalline lithium transition metal oxide-based powder and the B fraction(s) is(are) converted into a second lithium transition metal oxide-based powder and, and - Mixing the first and second monolithic lithium transition metal oxide-based powder to obtain the N(M)C-based positive electrode material.
