Efficient generation and transportation of energy is now the most important task of our time. Rechargeable battery systems using lithium-, sodium- or potassium-ions have received a great deal of attention in industry as well as academia due to their high energy density and reliability, but there are still some issues to be solved. In our laboratory, we are investigating the operating principle of batteries and researching to design more efficient energy storage systems.

The "active material" of the electrode primarily determines the energy density, power density, cycle life, and safety of the battery. So we can say that understanding the basics of active materials is of the utmost importance! Here we design and find next-generation materials to create a clean future.

The electrochemical reaction from the material is too complicated. We need to not only understand the charge transfer at the surface but also consider the ion diffusion in the solid. In addition, since the battery system is made up of many-body particle electrodes, unforeseen phenomena may be discovered. We understand the basics of electrochemical reactions.

How can we explore materials? In our lab, we use a variety of beam sources such as X-rays and neutrons to precisely analyze materials at the atomic level. Discover world-class analytics technology here.
