英文摘要	本文合成了掺铝富锂材料lI1.2Mn0.543CO0.078nI0.155Al0.030O2,并使用扫描电镜(SEM)、粉末X射线衍射(Xrd)、电感耦合等离子体原子发射光谱(ICP-AES)和拉曼散射光谱(rAMAn)等观察表征富锂和掺铝富锂材料.结果表明,共沉淀法合成掺铝富锂材料,具有r-3M空间群结构,Al元素进入晶格,未单独成相.电化学性能和非现场Xrd测试结果表明,4%(by MOlE)掺铝富锂电极100周期循环容量保持率83.7%,Al元素掺杂有利于容量的释放,增强了电极富锂材料的结构稳定性,提高了循环性能.; The Al-doped 0.5Li2MnO3·0.5Li(Mn0.4Co0.2Ni0.4)O2 compounds were successfully synthesized as cathode materials for lithium-ion batteries.The pristine and Al-doped materials were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),inductively coupled plasma-atomic emission spectrometry(ICP-AES) and laser Raman spectroscopy.The results indicated that all the prepared materials were indexed as a hexagonal structure with R-3m space group,and Al element had been introduced into lattice.When cycled at 180 mA·g-1(1 C-rate),the capacity retention of 4%(by mole) Al-doped 0.5Li2MnO3· 0.5 Li(Mn0.4Co0.2Ni0.4)O2electrode was as high as 83.7% after 100 cycles.The Al-doped materials could enhance the structural stability of electrodes,which contributes to high stabilized performance of cathode material for lithium ion batteries.; 国家重点基础研究发展计划项目(No.2007CB935603)资助
