概要

Battery is a key component to sustainable development that would increase energy efficiency and also enable fast adoption of renewable energies. The performances of batteries such as capacity, power, cycle life, safety and cost depend on the materials that are used inside. Prof. Yu’s research focuses on developing novel materials (cathode, anode, membrane and electrolyte) for energy storage applications and understanding their fundamental charge-discharge mechanisms and stability.

In a battery, ions are stored inside material structures, transported through interfaces and electrolyte, as well as reacted on surfaces. Our group uses advanced characterizations to study ion transports and charge-discharge mechanisms in various energy storage systems in order to develop technologies applicable for industry.

まとめ

Prof. Denis Yu received his A.B. (Physics) from Princeton University and PhD (Applied Physics) from Harvard University. After completing his PhD, he moved to Japan to work as an engineer at SANYO Electric Co. Ltd. for 8 years, developing cathode and anode materials for Li-ion batteries. Afterwards, he joined Nanyang Technological University and then City University of Hong Kong, and was promoted to associate professor in 2018. He joined the National Institute for Materials Science in 2022 and is now also an affiliated professor at the University of Tsukuba.
