摘要 用固相法合成富锂材料Li[Li0.2Mn0.54Ni0.13Co0.13]O2,通过包覆磷酸铋(Bi PO4)对材料进行表面改性,以提高循环稳定性。XRD、SEM及TEM测试结果表明,包覆材料Li[Li0.2Mn0.54Ni0.13Co0.13]O2/Bi PO4的结构与Li[Li0.2Mn0.54Ni0.13Co0.13]O2相比没有发生变化,Bi PO4均匀地包覆在材料表面,包覆层厚度约为10 nm。在2.0~4.8 V充放电,当电流为0.1 C时,制备的Li[Li0.2Mn0.54Ni0.13Co0.13]O2/Bi PO4的首次库仑效率从Li[Li0.2Mn0.54Ni0.13Co0.13]O2的75%提高到83%,以0.2 C循环100次,放电比容量保持在249 m Ah/g。 Lithium rich material Li[Li0. 2Mn0. 54Ni0. 13Co0. 13]O2was prepared by solid-state method,then modified by coating bismuth phosphate(BiPO4) to improve cycle stability. The results of XRD,SEM and TEM tests showed that the structure of coated material Li[Li0. 2Mn0. 54Ni0. 13Co0. 13]O2/ BiPO4 had no change compared to Li[Li0. 2Mn0. 54Ni0. 13Co0. 13]O2. BiPO4 was uniformly coated on the surface of the material with the thickness of 10 nm. When charged-discharged in 2. 0 ~ 4. 8 V,the initial Coulombic efficiency of Li[Li0. 2Mn0. 54Ni0. 13Co0. 13]O2/ Bi PO4 was improved from 75%(Li[Li0. 2Mn0. 54Ni0. 13Co0. 13]O2) to 83% when the current was 0. 1 C,the specific discharge capacity kept at 249 m Ah / g after 100 cycles at 0. 2 C.
