烧结参数对Ni0.5Mn0.5基正极的影响
Influence of sintering parameters on Ni0.5Mn0.5-based cathode
摘要
Abstract
This study aims to investigate the effects of sintering temperature and trace cobalt doping on the cathode material of lithium-ion batteries based on lithium nickel manganese oxide.Initially,the Ni0.5Mn0.5-based cathode materials were sintered at different temperatures(400,600,800,1 000℃),followed by phase analysis and morphological characterization.The results showed that with increas-ing temperature,the layered structure of the material improved,and the spherical morphology of pri-mary particles became more pronounced.Electrochemical performance testing results indicated that the sample sintered at 800℃exhibited the best comprehensive performance,while the sample sin-tered at 400℃showed a unique charge-discharge voltage plateau.When the voltage range was extend-ed from 3.0-4.5 V to 2.5-4.8 V,the 400℃sample showed a significant capacity increase.Subse-quently,1%cobalt was doped into the 400℃material,and electrochemical performance testing re-vealed that cobalt doping further improved the rate performance and cycling stability of the material.The results of this study provide important references for the process optimization and doping modifi-cation of Ni0.5Mn0.5 lithium metal oxide cathode materials.关键词
