Popis:	Li[Li2/10Ni1/10Co2/10Mn5/10]O2 was synthesized by a sol–gel method using glycolic acid as chelating agent. The prepared compound was subjected to XRD, SEM, cyclic voltammetry and charge–discharge analysis. The electrochemical studies reveal that the compound, Li[Li2/10Ni1/10Co2/10Mn5/10]O2, delivers a capacity of about 340 mAh g−1 during the first charging cycle with an irreversible capacity loss of 180 mAh g−1 and also undergoes capacity fading upon prolonged cycling. The cyclic voltammetry data are reflected in the charge–discharge studies. The effect of the dopants on the electrochemical properties of the compound is discussed.
