(IMAGE) Chalmers University of Technology Caption Battery researchers have long wanted to study lithium metal in a working lithium metal battery. Now researchers from Chalmers have developed a method to follow how the lithium in the battery cell behaves while cycling. With a specially designed cell and using X-ray tomographic microscopy, the researchers can observe the inner workings of the battery in real time in 3D. The new method may contribute to batteries with higher capacity and increased safety in our future cars and devices.
