Electrochemical features of LiNi0.33+δMn0.33+δCo0.33-2δO2 (0≤δ≤0.075) cathode materials for Li-ion batteries

Electrochemical features of LiNi0.33+δMn0.33+δCo0.33-2δO2 (0≤δ≤0.075) oxides (LNMCOs) have been studied as a function of the composition. The cation mixing was characterized by a set of methods including Rietveld refinement of XRD patterns and magnetic experiments. It is observed that the decreasing amount of cobalt favouring the presence of Ni2+ ions in the Li(3b) site affects the electrochemical performance of lithium cells.
