Overview

All our research topics.
Ion Correlations in Concentrated Liquid Battery Electrolytes

By measuring different transport parameters, such as ionic conductivity, Li+ transference number under anion-blocking conditions and salt diffusion coefficient, we characterize the ion correlations of concentrated liquid electrolytes for battery applications.
All-Solid-State Batteries

For a better understanding of solid-state batteries, we investigate the forming interfaces in different types of solid-state batteries.
Ion and Molecule Transport across the Solid Electrolyte Interphase (SEI)

The solid electrolyte interphase (SEI) is a passivation layer on the graphite anode of lithium-ion batteries. Ion, molecule and electron transport across the SEI is not well understood up to now. Therefore, we form SEIs on planar model electrodes, and we characterize their morphology and transport properties.
Characterization of Composite Electrodes for Solid-State Batteries by Electrochemical AFM Techniques

AFM-based electrochemical techniques are well suited for characterizing the electrochemical properties of materials at the nanoscale level. We are using such techniques for characterizing the electrochemical properties of composite electrodes for solid-state batteries.
