LiMn2O4 has been considered a promising cathode material for lithium-ion batteries in electric vehicles. However, there are still a number of problems of severe capacity fading before any materials modifications. Among all doped LiMn2O4, spinel LiNi0.5Mn1.5O4 material is seen as a potential cathode material for use in electric vehicles and energy storage systems in the future because of its high working...
Spinel LiNi0.5Mn1.5O4 and LiMn1.4Cr0.2Ni0.4O4 cathode materials have been successfully synthesized by the sol–gel method using citric acid as a chelating agent. The structure and electrochemical performance of these as-prepared powders have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and the galvanostatic charge–discharge test in detail. XRD results show that...
