Renaissance of the iron-air battery

Iron-air batteries promise a higher energy density than present-day lithium-ion batteries. Their main constituent, iron, is an abundant and cheap material. Scientists from Forschungszentrum J├╝lich are pursuing research into ...

Researchers clarify mystery about proposed battery material

Battery researchers agree that one of the most promising possibilities for future battery technology is the lithium-air (or lithium-oxygen) battery, which could provide three times as much power for a given weight as today's ...

How the electrodes of lithium-air batteries become passivated

Lithium-air batteries produce power from air, and are often called lithium-oxygen batteries. They are much lighter than lithium-ion batteries due to higher energy density. Lithium-air batteries have applications including ...

How to to bring lithium-air batteries closer to practice

Scientists from the Faculties of Materials Science and Chemistry, Lomonosov Moscow State University, are working on improvement of lithium-air batteries, which can significantly exceed the key parameters of lithium-ion systems. ...

New method increases energy density in lithium batteries

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method to increase the energy density of lithium (Li-ion) batteries. He has built a trilayer structure that ...
