Chemo-Mechanics of Battery Materials

The mission of our group is to uncover the fundamental mechanisms of deformation and degradation in battery systems and to leverage mechanical principles to design damage-resilient energy storage systems.

Our current focus is on lithium–based solid-state batteries, which exhibit a rich spectrum of chemo-mechanical challenges during electrochemical cycling, including lithium dendrite growth, void formation, and interfacial instability. To address these issues, we employ a multiscale experimental framework that integrates bulk mechanical testing (such as Tensile testing), microscale and nanoscale mechanical characterization (Multibeam optical stress sensor, Vickers microhardness testing and nanoindentation), and advanced microstructural analysis techniques (including cryogenic EBSD and cryogenic TEM). By correlating electrochemical behaviour with mechanical response and microstructural evolution across length scales, our research aims to establish mechanistic insights that enable the rational design of mechanically robust solid-state batteries.
