In situ investigation of electrochemical surface stress development in rechargeable batteries
… vs. lithium and sodium. There are two types of stress evolutions arising from lithiation/sodiation and delithiation/desodiation. Accommodating metal ion process makes compressive stress whereas stripping metal ion process makes tensile stress. These two types of stress evolution was measured by …

Interfacial processes in Li-ion batteries
… forms on both cathode and anode electrode surfaces. The composition and stability of the SEI to a large degree controls performance of the battery. This thesis investigates interfacial processes in Li ion battery electrodes as they relate to SEI, surface coverage, and structural properties. …
