富锂锰基Li1.2Mn0.54Ni0.13Co0.13O2正极材料的制备及电化学性能研究
Synthesis and electrochemical performance of Li1.2Mn0.54Ni0.13Co0.13O2 cathode material for lithium ion battery
摘要
Abstract
The layered Li1.2Mn0.54Ni0.13Co0.13O2 lithium-rich manganese-based solid solution cathode material was synthesized by a novel co-precipitation method.The structure,morphology and electrochemical performance of Li1.2Mn0.54Ni0.13Co0.13O2 were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM) and electrochemical tests.The results show that the material has a regular polyhedron shape with the particle size below 500 nm.This material can deliver a high initial discharge specific capacity of 209.0 mAh/g at the current of 18 mA/g within 2.0-4.8 V.After 50 cycles,the sample still can keep capacity retention of 87.7％.关键词
