摘要：
Electrochemical features of LiNi0.33+delta Mn0.33+delta Co0.33-2 delta O2 (0 <=delta <= 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-ion cells.
