Detection of lithium using SIMS on FIB microscope
The EQS spectrometer provides SIMS detection for focusedion beam (FIB) microscopes, with excellent sensitivity for light elements (sub ppm sensitivity for lithium).
Additionally, isotopically pure materials can be used for diffusion studies.

Lithium battery analysis The Micrograph shows a 50μm field of view of a cathode surface.
SEM imaging of an aged battery cathode shows bright regions.
SIMS imaging of this region shows the bright areas to be lithium rich.
