Using Cipher system to map the lithium content in Li-ion battery cathode materials

Cipher^® is used to map the lithium distribution in the scanning electron microscope (SEM). Through a combination of energy dispersive x-ray spectroscopy (EDS) and quantified backscatter electron (qBSE) imaging, the Li content in a metal-oxide cathode material is estimated. The mean Li content was found to be approximately 23.8 at.%.
