Characterization of multiple metals (Cr, Mg) substituted LiNi0.8Co0.1Mn0.1O2 cathode materials for lithium ion battery

► Cr-Mg substituted LiNi0.8Co0.1Mn0.1O2 was synthesized by fast co-precipitation. ► Rietveld refinements show that Cr-Mg substitution suppresses the cation-mixing. ► Cr-Mg substituted samples exhibit superior electrochemical performance.
