Imaging Method Reveals Lithium Batteries in Action

From Laboratory Equpiment:

Exactly what goes inside advanced lithium-air batteries as they charge and discharge has always been impossible to observe directly. Now, a new technique developed by MIT researchers promises to change that, allowing study of this electrochemical activity as it happens. The reactions that take place inside a conventional lithium-air battery are complex, says Yang Shao-Horn, an associate professor of mechanical engineering and materials science and enginee
