Battery Materials Analysis Group

Various important phenomena (e.g. chemical reactions, changes of crystal structure, plastic deformation, stress concentration and microcrack formation of active materials) take place in practical rechargeable batteries during charge/discharge reactions.

We conduct in situ characterization researches on those multiscale phenomena for the improvement of battery performance and durability.

The research includes observing physicochemical phenomena using electrochemical techniques coupled with various characterization techniques (e.g. x-ray absorption spectroscopy, x-ray photoelectron spectroscopy, scanning probe microscopy, etc), quantitatively examining theireffect on the battery performance and durability, and establishing the fundamental science to design highly efficient and durable materials.
