应用化学共沉淀法制备掺钌氢氧化钴复合材料,X射线衍射(XRD)、扫描电子显微镜(SEM)显示非晶态RuO2颗粒分散在六方晶系Co(OH)2薄片的表面.循环伏安、恒流充放电测试表明,Co/Ru=8/1的复合材料在碱性电解液中具有优良的电容性能和较高的比容量.
XRD and SEM showed that amorphous RuO2 particles were dispersed on the surface of the hexagonal Co (OH) 2 thin films by chemical coprecipitation method. The cyclic voltammetry The results of constant current charge and discharge tests show that the composite material with Co / Ru = 8/1 has excellent capacitance and high specific capacity in alkaline electrolyte.
