摘　　要：利用豆腐渣为模板,经煅烧处理后获得片层状的CuO产物,采用X射线衍射仪对样品进行物相分析,采用光电子能谱仪测定样品表面的元素成分。然后通过恒流充放电实验检测CuO的电化学性能,100次循环后充放电容量依然可高达520m Ah/g,均为一般商业碳电极材料的1.4倍,展现出了良好的循环寿命。以植物为模板制备的CuO产物能够有效地抑制充放电过程中的体积膨胀现象,减少粉化现象,具有优异的电化学性能,循环性能得到了很大改善,在锂离子电池负极材料领域中具有广阔的应用前景。A template prepared by soybean curb residue, the lamellar CuO product was got by calcination treatment ,the phase of the sample is analysised by X-ray diffraction, elements on the surface of the samples are measured by photoelectron spectrometer and then charge and discharge experiment testing the electrochemical performance of CuO via the constant current.The discharge capacity is still high 620mAh/g after 100cycles, that is about 1.4 times of general commercial carbon electrode material,which is showed good cycle life. CuO product template prepared by plants can effectively inhibit ti^e process of charge and discharge volume expansion phenomenon, reduce the phenomenon of the powder, has excellent electrochemical performance, the cycle performance is greatly improved , the production has broad application potential in the field of lithium ion battery anode materials.
