Modern life would be quite different without decent batteries. Can you imagine powering your laptop on something like a standard automobile battery? It simply doesn’t bear thinking about. Although we ...

Ten times more power than lithium ion — but still ten years off: A fluffy carbon electrode has brought scientists at Cambridge University a step closer to producing a workable lithium-air battery, but ...

Lithium-air batteries are devices, producing power just out of air so they are also called lithium-oxygen batteries. Due to higher energy density they are much lighter than lithium-ion ones.

Current lithium batteries are based on intercalation—lithium ions squeeze into spaces within electrode materials such as graphite. As a result, most of the battery’s volume and bulk is dedicated to ...

A research team has developed lithium-air batteries with very high electric storage capacity15 times greater than the capacity of conventional lithium-ion batteries using carbon nanotubes (CNT) as an ...

The National Institute for Materials Science (NIMS), in collaboration with Seikei University, has successfully enhanced the power output of lithium-air batteries, which are attracting attention as ...

Correction: On Dec. 8, 2014, this story was changed to correct the explanation for how the researchers improved the Li-air battery’s performance. As engineers look for ways to power electric cars that ...
