One of the world’s highest energy densities achieved. NIMS and Softbank Corp. have developed a lithium-air battery with an energy density over 500Wh/kg – significantly higher than currently lithium ion batteries. The research team then confirmed that this battery can be charged and discharged at room temperature. In addition, the team found that the battery developed by the team shows the highest energy densities and best cycle life performances ever achieved...

A NIMS team led by Yoshimi Kubo and Akihiro Nomura, team leader and researcher, respectively, Lithium Air Battery Specially Promoted Research Team, C4GR-GREEN, developed lithium-air batteries with very high electric storage capacity 15X greater than the capacity of conventional lithium-ion batteries using carbon nanotubes (CNT) as an air electrode material. Demand for rechargeable batteries is expected to increase rapidly as electric vehicle power sources and joint sources of household electricity with solar cells.

The current lithium-ion batteries have advantages of being compact, producing h...

Dr. Kyeongjae Cho, professor of materials science and engineering in the Erik Jonsson School of Engineering and Computer Science, has discovered new catalyst materials for lithium-air batteries that jumpstart efforts at expanding battery capacity. Lithium-air (or lithium-oxygen) batteries “breathe” oxygen from the air to power the chemical reactions that release electricity, rather than storing an oxidizer internally like lithium-ion batteries do...
