Metal Oxide-Based Nanostructure Arrays for Electrochemical Energy Storage Devices(1)

2014中国功能材料科技与产业高层论坛——Supercapacitor has potential applications in portable electronics, backup power sources, large -scale elec¬tric vehicles and microelectronic devices. Electrode materials are one of the key aspects determining the performance of supercapacitors. Recently, metal ox¬ide-based pseudocapacitive materials have attracted much attention due to their high theoretical capaci-tance. In this talk, I will mainly discuss the superca¬pacitor application of pseudocapacitive hybrid nanos¬tructure arrays grown directly on current collector substrates. By selecting electrode materials with high specific capacitance, ordered core-shell or hierarchi¬cal hybrid nanostructures can be rationally designed, which leads to synergistic improvement in terms of electrical/ionic conductivity and stability. Novel elec¬trode materials with high capacitance, long cycle life and exceptional rate capability can thus be obtained. I will further show that these binder -free nano array electrodes are promising for high -performance two - electrode supercapacitor devices.
