摘要: Abstract The LiMnPO 4 ·Li 3 V 2 (PO ) /C composite cathode material was synthesized from Mn(VO nanosheet precursor, which prepared by a hydrothermal method. structure and morphology of the were systematically investigated powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission microscope (TEM) (STEM), etc. exhibits low polarization high specific capacity 150.7 mAh g −1 at 0.1C in voltage range 2.5–4.5V, excellent cycle rate performance for its stable nanocomposite framework. dominantly exists morphological shape nanograins nanorods, increases surface area hence facilitate electrolyte penetration. nanoparticle components even further identified detail.
