Some materials show ionic conduction, even though they are solids, which are called solid electrolytes. Use of solid electrolytes makes batteries to have long life and, especially in the case of lithium batteries, completely overcome their safety issues originated from their combustible organic electrolytes. Studies in Rechargeable Battery Materials Group are aiming at the development of such solid-state batteries.

Specialized Research Field

High performance of batteries will come not only from high-performance battery materials but also from high-performance interface, which will not be realized without understanding of the interfacial phenomena. Our studies so far have revealed that such interfacial phenomena, which are caused by anomalous ionic conduction in space-charge layer formed at the interface, play a critical role in the battery performance. We have also developed a novel interfacial design based on the space-charge mechanism and succeeded in enhancing the performance of solid-state batteries to be comparable to commercial lithium-ion batteries.
