An x-ray microscopy recently developed at the department of energy's Lawrence Berkeley National laboratory has given scientists the ability to image nanoscale change inside lithium-ion battery particles as they charge and discharge.
The real time images provide a new way to learn how to improve them. The scientist used the approach to image Micron-sized battery particles as lithium ions migrate in and out of the particles .The images chronic the evolution of the particles chemical composition and reaction rate as a nanoscale spatial resolution and a minute by minute time resolution .
A phenomenon that likely curbs battery performance over time. This and other insight obtained from the imaging technique could help research ers improve batteries for electric vehicles,as well as smart phones,laptops,and other devices.
