| 摘要: 以氯化钴为原料、氨水(28wt%)为沉淀剂采用均匀沉淀法成功地合成了Co(OH)2。X-射线衍射(XRD)、扫描电镜(SEM)测试表明，表面活性剂Tween-80的加入使所制备的α-Co(OH)2呈现出类似花朵的形貌;循环伏安、恒电流充放电、交流阻抗和循环寿命等电化学测试表明，该材料的电化学性能也得到一定的提高，其单电极比电容可达到370 F·g-1。 |

| Abstract: Co(OH)2 particles were prepared with CoCl2 as the raw material and NH3·H2O(28wt%) as the precipitation agent by homogeneous precipitation method. The flower like α-Co(OH)2 obtained by the addition of surfactant Tween-80 was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrochemical tests show that this material has a better capacity， and its specific capacitance as single electrode is up to 370 F·g-1. |
