以乙酸锰、乙酸钴、草酸为原料，采用微通道反应器共沉淀法合成了花朵状的钴掺杂氧化锰（Mn1-xCoxO）锂离子电池负极材料。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、X射线光电子能谱（XPS）对电极材料的结构、形貌和元素状态进行了表征。采用恒流充放电测试和电化学工作站研究了钴不同掺杂量对一氧化锰负极材料电化学性能的影响。研究发现，随着钴掺杂量逐渐增加，Mn1-xCoxO由棒状演变为花朵状结构，比容量随着钴掺杂量增加先增加后下降。合成的Mn0.95Co0.05O在5C倍率下循环200次后放电比容量为496.7 mA·h/g，与未掺杂的一氧化锰相比其比容量提高约40.0%，显示出较好的电化学性能。

Flower like Co-doped manganese oxide（Mn1-xCoxO） lithium ion battery anode material was synthesized by co precipitation method in the micro channel reactor，using Mn（CH3COO）2·4H2O，Co（CH3COO）2·4H2O and C2H2O4·2H2O as raw materials.X-ray diffraction（XRD），scan electron microscopy（SEM） and X-ray photoelectron spectroscopy（XPS） were used to characterize the structure，morphology and elemental state of Mn1-xCoxO electrodes.Galvanostatic charge-discharge test and electrochemical workstation were carried out to investigate the effect of Co-doping amount on electrochemical perfor mance of Mn1-xCoxO as an anode material for lithium ion batteries.When the amount of Co-doping increased，Mn1-xCoxO and its precursor all evolved from rod like to flower like，and the capacity first increased and then decreased.As synthesized Mn0.95Co0.05O delivered a discharge capacity of 496.7 mA·h/g after 200 cycles at 5C rate，and its discharge specific capacity was increased by about 40.0% compared with undoped MnO，which showed good electrochemical performance.
