Forschung

A promising direction for next-generation rechargeable batteries is the lithium metal battery, which uses solid lithium metal as the anode. Lithium metal is interesting because it offers a very high theoretical capacity (3860 mAh/g or 2061 mAh/cm³) and a low electrochemical potential (-3.04 V vs. SHE). he challenge, though, is that these benefits are difficult to realize in practice because the solid electrolyte interphase (SEI) that forms on the lithium surface isn’t very stable.

My work focuses on this SEI layer. I use Kinetic Monte Carlo simulations to look at how it forms at the molecular scale. This helps me understand how factors like viscosity, permittivity, and the degree of salt dissociation influence the development of the SEI over time.
