Advanced Battery Research Group

High-performance rechargeable battery systems are imperative to meet the increasing demand for energy storage devices that can be used, for instance, to load-level the power output fluctuations for renewable energy sources and electric cars. To develop the next-generation rechargeable battery systems that confer various performance metrics such as high reliability, high levels of safety, high energy/power density and low cost, this research group focuses on metal anode materials and conversion electrode materials. In addition, emphasis is also placed on the development of new electrolyte materials such as by using ionic liquid or polymer, analysis of the degradation mechanisms of sulfide solid electrolytes, electrochemical analysis methods including electrochemical impedance spectroscopy, and technologies that control the electrode/electrolyte interface to improve the charge/discharge reversibility.
