摘要: coated materials have been synthesized as positive electrode materials for lithium-ion batteries. The pristine and-coated materials were characterized by X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, and charge–discharge techniques. The electrochemical studies indicated that the-coated showed initial irreversible capacity loss of only compared to for pristine material. Meanwhile, the coated material also exhibited better rate capability and cyclic performance, which has higher capacity retention …
