Professor Atsuo Yamada

Department of Energy and Environmental Materials

The University of Tokyo, Japan

Atsuo Yamada is professor at the university of Tokyo since 2009, known as one of the earliest explorations of LFP cathode research, having published the first report on room-temperature theoretical capacity operation of LiFePO4 in 2001. Also, his discovery of Alluaudite Na2Fe2(SO4)3 in 2014 is now on mass production in market. More recently, his work is extended to identification of several functional electrolyte as well as the liquid Madelung theory that can replace the 100 years of Debye-Hückel theory. He has published over 280 refereed journal papers exceeding 44,000 citation, ranked as a Highly Cited Researcher. Among his many honors, Atsuo has been awarded the Spriggs Award and the Purdy Award from ACerS, the Scientific Achievement Award from ECS Japan, and IBA Research Award from International Battery Association, Battery Division Research Award from the Electrochemical Society, Science &Technology award from MEXT Minister.

Case study

Advancement in Sodium-ion Battery

Sodium-ion batteries are experiencing a rapid technological evolution, solidifying their position as the leading alternative to lithium-based chemistries for stationary storage and urban electric vehicles. Recent breakthroughs in cathode design—specifically polyanionic compounds and Prussian blue analogues—along with hard carbon anode optimization have significantly boosted energy density and cycle life. Leveraging abundant, geopolitically secure raw materials, this technology mitigates critical supply chain risks while offering superior low-temperature performance and inherent thermal safety. As manufacturing lines achieve gigawatt-scale production, sodium-ion technology is successfully bridging the gap between cost efficiency and reliable, large-scale clean energy transition.
