WO3/PbO2电极材料复合共沉积工艺条件优化研究

Study of process condition optimization for the WO3/PbO2 electrode materials

为提高PbO2的电容性能,采用复合共沉积法将纳米WO3粒子掺杂进PbO2基质中,制备得到WO3/PbO2复合电极材料.利用扫描电镜及电化学测试等分析方法,详细研究了沉积温度、沉积电流、粒子浓度及搅拌程度等工艺条件对材料形貌及电容性能的影响,并进一步优化了工艺条件.

The nano-WO3 was imbedded into the PbO2 matrix for increasing the pseudocapacitance of PbO2.The WO3/PbO2 composite electrode materials were prepared by the composite electrodeposition method.The influences of process conditions such as the electrodeposition temperature,electrodeposition currents,concentration of the particles and stirring,on the morphology and the capacitance performance of the composite material were investigated by scanning electron microscope(SEM)analyses and electrical tests.Furthermore,the process conditions were optimized for the composite electrodeposition of the WO3/PbO2 composite electrode.
