Effect of Al and Fe Doping on the Electrochemical Behavior of Li_1.2Ni_0.133Mn_0.534Co_0.133O₂ Li-Rich Cathode Material.

ABSTRACT: This article studies the doping of Li-rich cathode materials. Aluminum and iron were chosen as dopants. Li-rich cathode materials for lithium-ion batteries, which were composed of Li_1.2Ni_0.133Mn_0.534Co_0.133O₂ with a partial replacement of cobalt (2 at %) by iron and aluminum, were synthesized. The dopants were introduced at the precursor synthesis stage by co-precipitation. The presence of Fe and Al in the composition of the synthesized samples was proved by inductively coupled plasma mass spectrometry, X-ray diffraction analysis and X-ray microanalysis. The cathode materials were tested electrochemically. The incorporation of Al and Fe into the structure of lithium-enriched materials improved the cyclability and reduced the voltage fa
