Surging world energy demand and diminishing reserves of fossil fuels have intensified the pursuit for green, high-performance, cost-effective and sustainable energy storage technologies. Batteries that store high-energy densities play a large role in the implementation of green energy technologies and non-petroleum vehicular mobility. Whereas Li-ion batteries offer the highest energy density among present battery technologies, there are still challenges remaining to be solved such as limited Li sources, cost, safety and stability. Alternative rechargeable battery systems with transporting ions beyond Li (e.g., Na+) have attracted renewed interests in recent years due to their low cost, abundance, and environmental benignity. However, identifying suitable electrodes in these emerging systems remains a scientific challenge.

Size and morphology are crucial factors that can affect the electrochemical properties of an electrode. Nano-sized electrode materials with different morphologies have shown improved kinetics and mechanical strength compared to their bulk counterparts. Thus, the objective of the Xiong Research Group is to develop nano-architectured electrode materials, with precisely-controlled properties, to meet the energy storage and conversion challenges. The current research interests in the Xiong Group include but not limited to:

  • Electrochemical Synthesis of  Nanostructured Electrode Materials with Controlled Size and Shape
  • Advanced Functional Electrode Materials for Alternative Battery Systems (e.g. Na-ion batteries)
  • Irradiation Effect on Electrode Materials
  • In-situ Characterization of Electrochemical Processes at Electrode Materials
  • Electrochemical Peudocapacitors
  • Nanostructured Electrocatalysts
  • Hybrid Energy Storage System
