Nanomaterial design
My research endeavors focus on the design and synthesis of a diverse range of nanostructured materials. This is accomplished through the utilization of innovative synthetic methods, including spray process, electrospinning process, wet-chemical process, and hydro/solvothermal reaction. By fine-tuning the characteristics of the synthesized nanomaterials such as morphology, chemical composition, and size, we can custom-design their functionality to suit a wide array of applications including energy storage, catalysis, sensors, etc.

Metal-ion batteries, metal-chalcogen batteries
In our daily lives, Lithium-ion batteries have emerged as the predominant focus of energy storage research, owing to their high energy density, long cycle life, and low self-discharge property. Furthermore, relentless efforts have been put into investigating next-generation batteries, which include sodium- and potassium-ion batteries and metal-chalcogen batteries. Also, aqueous batteries including zinc-ion batteries have received considerable research interest for their high safety and environmental benignity. ​Adopting novel nanostructured electrodes can significantly enhance the electrochemical properties of various systems.
Advanced electrolyte design
Electrolyte design is a powerful tool for boosting the electrochemical properties of rechargeable batteries. Introduction of additives or co-solvents is a promising approach to achieve high electrochemical properties at high voltage by regulating the cathode-electrolyte interphase and preventing detrimental side reactions. My research utilizes a high-throughput liquid handling robots for developing a novel electrolyte that has high electrochemical oxidative stability.
All-solid-state batteries
The advent of electric vehicles has led to an increase in demand for safer rechargeable batteries with high energy densities. Currently dominant lithium-ion batteries might face certain safety concerns, such as thermal runaway and explosions, resulting from the potentially flammable nature of organic liquid electrolytes. All-solid-state batteries that make use of solid electrolytes is considered as a promising alternative due to their safety and potential to surpass the energy density of current lithium-ion batteries. My research focuses on achieving high energy density all-solid-state batteries with long cycle life.
