Title: Defect Engineering of Metal Oxide Materials for Energy Storage


Transition metal oxide-based supercapacitors are one of the most efficient classes of electrochemical storage devices because of their higher power density, faster charge–discharge rate, and longer lifespan than those of lithium-ion batteries. Generally, transition-metal oxides involve fast reversible Faradaic reactions at the surface or at a near-surface region, producing high energy densities. However, the high energy density of transition-metal oxides is achieved by sacrificing power density and cycling lifetime, impeding their large-scale practical application in supercapacitors. In tackling these problems, several approaches have been explored. For instance, surface modification, doping, and defect engineering of transition metal oxides have been considered an effective strategy to accelerate and intensify reaction kinetics, realizing high electrochemical performance. In this talk, the speaker will present his recent work in the development and application of nanostructured metal oxide electrode for high-performance supercapacitors. Several strategies, including the morphology control, core/shell architecture, and defect engineering, will be discussed to improve the electron transports, electrolyte ions diffusion kinetics, and electrical conductivity of metal oxide electrodes.
