Moving electrode electrochemical impedance spectroscopy

, 2023
Electrochemical impedance spectroscopy (EIS) is a powerful tool for analysing material properties and studying interfacial electrochemical processes. During measurement, the sample is contacted via electrodes, and impedance as a function of frequency is determined by applying an AC voltage and measuring the resulting current. In conventional EIS, where

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr

Advanced Functional Materials, EarlyView.
We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...
