文摘

Li1.2Ni0.2Mn0.60O2/C composite material was prepared by one-pot solid-state method. 1D a-MnO2 nanowires and microsphere hollow b-Ni(OH)2 were prepared by a hydrothermal method. 1 wt.%LLTO-coated composite showed the best performance among samples. LLTO layer not only improves the ionic transport of Li-rich oxide material, but also prevent Li-rich material corrosion.
