Cycling performance of Li[Li2/10Ni1/10Co2/10Mn5/10]O-2 synthesized by sol-gel route
Li[Li2/10Ni1/10CO2/10Mn5/10]O-2 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]O-2, 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. (c) 2006 Elsevier B.V.
