Application of Analysis with Muonic X-rays for Battery

Abstract

We have applied an elemental analysis with muonic X-rays to an aluminum-laminated Li-ion battery. As a result, the metallic Li deposition on the graphite anode was successfully detected. We also demonstrated that the location of the deposition could be identified from the depth profile. This is expected to be useful in R & D for reuse and further safety of a Li-ion battery.
