Preparation and characterization of Cr-doped LiMnO2 cathode materials by Pechini's method for lithium ion batteries

Journal Article


Abstract


  • o-LiMnO2 and LiMn1-xCrxO2 (x = 0.05 and 0.1) powders are synthesized via Pechini's method. Crystalline structure, surface morphology, and electrochemical properties of the prepared powders are investigated by XRD, SEM, cyclic voltammetric and capacity retention studies. From results, it is found that a small amount of Cr-doping into LiMnO2 cathode can not only lead to a topographic change from orthorhombic to monoclinic geometry and particle size reduction, but also improve cycling performance and reversible capacity.
