In recent years, there has been a lot of interest in the use of nanotechnology fabrication and analytical methods for designing and studying electrochemical energy storage technologies. The primary reason for this is that many critical processes that govern the overall performance of these macroscale technologies (batteries) take place on the nanoscale. In our lab, we're attempting to understand these processes at the nanoscale level and gain control over them by employing various fabrication and synthetic methods.
Research
Solid-State Li Metal Batteries
Solid-state batteries hold immense potential for safer, high-energy-density storage. However, achieving solid-state electrolytes with high ionic conductivity, interfacial stability, and mechanical strength remains a challenge. Our lab focuses on designing and analyzing multiphase organic (polymers), inorganic (ceramics), and hybrid electrolytes. Using advanced electrochemical, microscopic, and spectroscopic techniques, we investigate these materials at all stages—pre-operation, in situ, and postmortem—providing insights to optimize material properties for improved performance.
Nanoelectrochemisrtry
While batteries operate on a macroscale, their performance and stability are dictated by interfacial processes at the nanoscale. Understanding these processes at relevant scales is crucial for advancing battery research. Our lab employs advanced nanofabrication techniques to create electrochemical systems with precise ionic channels and interfaces, enabling in-situ observation and monitoring of nanoscale chemical and electrochemical phenomena.
Beyond Lithium
Transitioning to a greener economy demands large-scale energy storage solutions. While lithium-based batteries offer high energy density, their widespread use in electromobility and electronics drives up costs and limits availability. Our lab explores alternative technologies, such as sodium (Na) and zinc (Zn) metal batteries, which promise low cost, simplicity, and long lifespans, making them ideal for large-scale storage applications.
