采用水热合成法制备了具有蒲公英状中空结构的高孔氧化铜微球。采用x射线衍射、扫描电镜、恒流电池循环和循环伏安法对该独特的氧化铜粉末的结构和电化学性能进行了表征。该CuO电极具有稳定的良好容量保持能力，在多达50次循环中可逆容量超过600mAhg−1。该方法适合于大规模生产这些空心氧化铜微球，具有实际应用价值。
Highly porous microspheres of CuO with a dandelion-like hollow structure were prepared by a hydrothermal synthesis method. X-ray diffraction, scanning electron microscopy, galvanostatic cell cycling and cyclic voltammetry were employed to characterize the structure and electrochemical performance of this unique CuO powder. This CuO electrode showed stable good capacity retention with a reversible capacity of over 600mAhg−1during up to 50 cycles. This method may be suitable for larger-scale production of these CuO hollow microspheres for practical applications.
