Synthesis of Li-ion Battery Cathode Materials Based on Lithiated Transition Metal Oxides by Spray Method

Abstract

The parameters of synthesis by the spray method of cathode materials Li1.2Ni0.13Co0.13Mn0.54O2 and Li1.25Ni0.12Co0.12Mn0.51O2, differing in lithium content were studied. The phase and granulometric composition, the morphology of the powder particles obtained, as well as an influence of temperature, total metal concentration, and pH of the solution on the properties of powders of cathode materials were studied. The discharge capacities of the obtained materials reached 260 mAh g‒1 in the range of 2.5‒4.8 V.
