<About the Research>
Rechargeable batteries, which can store electricity and discharge it whenever needed, have become an indispensable device in our daily lives for applications such as smartphones and laptop computers. Recently, the demand for high-performance and high-safety rechargeable batteries has been increasing for electric vehicles and power storage applications, and they are attracting attention as an essential technology to realize a low-carbon society.
   We are developing new materials and reactions for advanced lithium-ion batteries and post-lithium-ion new batteries. Particularly, we focus on an electrolyte, which transports ions between positive and negative electrodes. We control ion-molecule coordination states in a liquid phase to develop unique properties and functions that are not found for conventional electrolyte materials. We are also exploring the possibilities of various new rechargeable batteries based on the new functions and properties we have discovered. For example, we have developed high-voltage batteries (4.7 V vs. 3.8 V for commercial Li-ion batteries) by enhancing the voltage resistance of the electrolyte, quick-charge batteries using a unique electrode/electrolyte interface, non-flammable lithium-ion batteries using a flame-retardant and even fire-extinguishing organic electrolyte, and new water-based high-voltage batteries by stabilizing water from electrolysis. We will continue to explore unknown properties and functions of electrolyte materials and develop new rechargeable batteries that will solve environmental and energy issues.
