Better Batteries -- X-ray technique reveals irregularities and dead spots arise due to incomplete lithium stripping from anode during battery
Clues to Better Batteries — X-ray technique reveals irregularities and dead spots arise due to incomplete lithium stripping from anode during battery discharge.
“The x-rays can see right through the battery and allow us to make many measurements very quickly to track what happens as the battery changes,” Khalifah said. “To the best of our knowledge, no one has ever been able to use x-rays to map lithium shuttling while it happens.” “We made the maps while the battery was in a resting state, starting at zero capacity, then took pixel measurements as we charged to half capacity. Then we stopped charging and made another map, then resumed pixel-specific measurements while charging to full capacity. We then discharged the cell while continuing to alternate mapping and pixel scans, stopping to collect maps at half discharge and full discharge,” Khalifah explained.
“In general, one expects it is more difficult to deposit lithium metal as the atoms have to be organized in the specific arrangement of the crystal structure of this metal,” Khalifah explained. “Removing lithium should be easier because any atom on the surface can be taken away without having to follow any specific pattern.
