Summary:
The rapid development of renewable energy such as solar and wind needs high-performance and sustainable energy storage technologies. Electric energy can be stored in electrochemical energy storage systems, such as lithium-ion batteries (LIBs). However, increasing utilization of lithium is pushing up the price of lithium resources. Electrochemical energy storage systems based on sodium ion as the charge carrier are gaining fast growing research interests. However, the substitution of lithium by sodium leads to quite a number of differences in terms of electrode materials and the physics and chemistry underlying cell configuration and operation. Over the past few years, my lab has been working on anode materials for sodium-ion storage with an ultimate goal of developing sodium-ion battery and sodium-ion capacitor technologies. In this talk, I will discuss our recent research on innovative electrode materials potentially suitable for sodium-ion storage, as well as charge storage mechanism.
