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.
