化学镀镍包覆提高尖晶石LiMn2O4的高温性能
Elevated temperature performance of spinal LiMn2O4 with electroless plating nickel
【摘要】 尖晶石LiMn2O4是最有希望代替钴酸锂的锂离子蓄电池正极材料,高温下容量衰减严重是其得以广泛应用的瓶颈。采用化学镀镍包覆方法对尖晶石LiMn2O4进行了表面改性。通过X射线衍射(XRD)和扫描电子显微镜(SEM)等方法对改性后的尖晶石表面进行了研究。电化学测试结果表明化学镀镍包覆方法能大幅度提高Li-LiMn2O4电池的高温性能。
【Abstract】 As an attractive cathode material for Li-ion battery, spinal LiMn2O4 cycling performance at elevated temperature was urgent. The modification of spinal LiMn2O4 with electroless plating nickel was studied. The surface of spinal LiMn2O4 coated with nickel was studied by SEM and XRD. The results show that the modification enhances greatly the elevated temperature performance of spinal LiMn2O4.
