LiMn1−1.5xCexPO4/C (x=0, 0.01, 0.03, 0.05) are synthesized by an efficient solvothermal synthesis in water/diethylene glycol system. The structures and morphologies of all samples are studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). X-ray photoelectron spectroscopy (XPS) results suggest that trivalent Ce3+ doping has no influence on...
La0.7Sr0.3Mn0.7Co0.3O3-coated spinel LiMn2O4 with excellent cycle stability and high rate capability is successfully prepared by a sol–gel method. The 3 wt.% La0.7Sr0.3Mn0.7Co0.3O3-coated LiMn2O4 shows the optimum electrochemical performance. It can deliver 101 mAh g−1 at 10 C even after 100 cycles with a capacity retention of 93.5%. In contrast, the bare LiMn2O4 delivers 83.6 mAh g−1 at the same...
