- The study investigates the formation of zinc vanadium oxide (ZVO) and zinc hydroxy-sulfate (ZHS) as discharge products in sodium vanadium oxide (NVO) cathodes with two different morphologies, NVO(300) and NVO(500), using X-ray diffraction techniques.
- It finds that ZHS formation is more prominent at higher current densities and can be reversed during charging, while ZVO formation happens at lower current densities and persists throughout the discharge cycles.
- The research utilizes synchrotron-based energy dispersive X-ray diffraction (EDXRD) to reveal reversible changes in the NVO structure during discharge, showing distinct formation patterns for ZVO and ZHS based on their
