Real-time dynamics during recharging cycles

Abstract

This paper describes preliminary results from in situ electrochemical atomic force microscopy (EC AFM) and in situ electrochemical small angle x-ray scattering (EC USAXS) studies. Experiments are designed to quantify the morphological evolution during charge and discharge cycles. From the AFM data we measure feature shapes, nucleation density, island distributions and quantify surface roughness using height-height correlation functions. The USAXS scattering data is modeled as a distribution of islands. The goal of our project is to link early time nucleation events with the onset of large-scale instabilities such as dendrites. © The Electrochemical Society.
