In Situ Imaging and Phase Analysis of Live Cell Lead Battery Materials for Auxiliary Battery Cycling Regimes
Partners
University of North Texas, Ecobat and East Penn Manufacturing (USA)
Duration
January 2023 – present
Objective
This project aims to investigate the processes occurring at microscopic level during representative tests for auxiliary batteries to understand how positive and negative electrodes change during different charge conditions
Research priority
Analyze structural changes of battery electrodes during representative auxiliary battery tests

Initial results
• Measurements were performed on legacy samples using X-ray microscopy (XRM) paired with micro-computational tomography (μCT)
• Preliminary synchrotron X-ray diffraction (SR-XRD) experiments were performed alongside operando experiments
• Phase identification of the preliminary XRM measurements is underway
• 2V cells are in preparation to optimize experimental setup for in-situ measurements
