题目:Energy Storage Enabled by Engineering Carbon Nanostructures






Sustainable and renewable energy sources from hydropower,solar energy, and wind powerare expected to release the heavy burdens on the current energy infrastructure and the environmental concerns. As these renewable energy sources such as solar energy and wind power are intermittent in nature, reliable electrochemical energy storage (EES) systems, mainly including rechargeable batteries and electrochemical capacitors, are purposely explored to promote efficient utilization of these energy sources and are a growing challenge. The development of high energy storage devices has been one of the most important research areas in recent years and relies mostly on the successful engineering of electrode materials. Carbon nanostructures such as carbon nanotubes (CNTs) and graphene have been full of surprises since their emergence and are intensively investigated for use as electrode materials in energy storage devices. Utilizing CNTs, graphene, and their composites for various energy storage applications such as lithium ion batteries and super-capacitors are under close scrutiny because of their improved electrochemical activity, cost effectiveness, environmental benign nature, and promising electrochemical performance. In this presentation, I will discuss our research strategies and efforts to engineer carbon nanostructures for different energy storage applications.
