In our lab, we master both the traditional slurry process and solvent-free dry process manufacturing for Li-ion batteries. By precisely tuning the flow behaviour of slurries, we can coat them onto current collectors at high mass loadings while successfully mitigating the cracking and delamination. At the same time, we are actively redefining the limits of energy density by pioneering dry electrode manufacturing to completely eliminate toxic solvents and massive drying infrastructure. To build these next-generation, solvent-free electrodes, our group leverages two techniques: PTFE fibrillation and electrostatic deposition spray coating (ESD). 

We also conduct research on the synthesis and development of lithium-rich cathode materials for lithium-ion batteries, aiming to enhance energy density, improve electrochemical performance, and reduce overall battery costs for next-generation energy storage applications.

In our lab, we look at zinc not just as an element but as the cornerstone for the next generation of sustainable energy storage. Zinc is globally abundant, highly recyclable, and fundamentally safe, utilizing non-flammable, water-based electrolytes that completely eliminate the fire risks associated with conventional battery chemistries. By diving deep into zinc battery development, our group is tackling the core material challenges—like preventing localized crystal growths (dendrites) and side reactions—that have historically limited its cycle life.

Understanding how materials behave at different length scales is essential for developing next-generation energy storage technologies. In our laboratory, we utilize advanced characterization tools such as atomic force microscopy (AFM), nanoindentation, and microindentation to investigate the surface, mechanical, and interfacial properties of a wide range of materials, including battery electrodes and solid electrolytes.

We also investigate the limitations of NaSICON-based solid electrolytes, Na₁₊ₓZr₂SiₓP₃₋ₓO₁₂ (0 < x < 3), using molten sodium symmetric cells. A key focus of our research is understanding the formation of metallic sodium dendrites, which can penetrate the solid electrolyte and cause premature cell failure.
