OKUBO, Masashi

Electrochemical energy storage (EES) devices such as lithium-ion batteries and capacitors, which allow us to access to electricity anywhere and anytime, are widely deployed in our society. Okubo laboratory is conducting research and development of future EESs, for instance, with higher efficiency, higher energy, or higher power. For example, batteries, which store/supply electric energy at high density, play a major role in off-the-grid power sources. However, lithium-ion batteries face many challenges such as energy density, power density, cost, safety, and resource sustainability. We aim to develop, for instance, electrode materials that efficiently store/supply electric energy, and electrolytes/interfaces that transmit electric energy without loss. We will create materials that realize novel-concept next-generation batteries such as sodium-ion batteries, aqua batteries, and anion batteries.
