Abstract
Lithium-rich transition metal complex oxides of the general composition xLi2MnO3• •(1–x)LiMO2 (M = MnaNibCoc, a + b + c = 1) were synthesized by coprecipitation and modified Pechini method. The influence of the oxide phase composition on their electrochemical performance as cathode materials was studied in lithium half-cells. Effects of the synthetic approach and synthesis conditions on the morphology and electrochemical characteristics of the materials obtained were considered. The composition 0.35Li2MnO3• •0.65LiMn1/3Ni1/3Co1/3O2 demonstrates the highest discharge capacity retention during cycling. The samples with discharge capacity of 290 mA h g–1 were obtained.
