摘要
以LiAc·H2O、Ni(Ac)2·4H2O和Mn(Ac)2·4H2O为原料,制备了锂离子电池层状正极材料Li[Li0 2Ni0 2Mn0 6]O2。XRD分析表明:其晶体结构为典型的αNaFeO2型层状结构。该材料的初始容量大于220mAh/g,100次循环后,仍大于210mAh/g,展示了较高的比容量和良好的循环性。
Layered Li[Li_(0.2)Ni_(0.2)Mn_(0.6)]O_2 which used as cathode material for Li-ion battery was synthesized by LiAc·H_2O,(Ni(Ac)_2·4H_2O) and Mn(Ac)_2·4H_2O as raw materials. XRD analysis showed that the material could be indexed by a hexagonal (α-NaFeO_2) layer structure. The initial capacity of the material was higher than 220 mAh/g and more than 210 mAh/g after 100 cycles and it exhibited high discharge capacity and good cycle performance.
