摘要
以Li2CO3,MnO2和Ni(OH)2·H2O为原料,采用机械力化学法制备锂离子层状结构正极材料LiNi0.5Mn1.5O4,采用X射线衍射,扫描电镜对其结构和形貌进行了表征。结果表明粉磨6h可制备能在较低温度下发生固相反应的前驱体;前驱体于800℃煅烧6h制备得到具有α-NaFeO2型层状有序结构的单相LiNi0.5Mn1.5O4。样品的首次放电容量为80 mAh·g-1。
Cathode material LiNi0.5Mn1.5O4with layered structure was synthesized using Li2CO3,MnO2 and Ni（OH）2 as starting materials by mechano-chemical method.The results indicated that precursor which could easily occur solid-state reaction at low temperature could be obtained by grinding for 6 h;LiNi0.5Mn1.5O4 cathode materials with α-NaFeO2 types layered structure was prepared by calcined at 800 ℃ for 6 h from precursor.The initial discharge capacity of LiNi0.5Mn1.5O4 is 80 mAh/g.
