Summary: As the need for low-cost and high-capacity materials increases, attention is turning towards Mn-based Na4MnV(PO4)3 positive electrode materials for Na-ion batteries, which allow multiredox reactions. However, the structure deteriorates rapidly when the third Na+ is extracted at high voltage, leading to poor cyclability. This study used synchrotron-based operando techniques to analyze the structural changes during the extraction of the third Na+ and found significant modifications in the crystal structure and local environments of Mn and V. These findings provide important insights into the electrochemical performance of multiredox NASICON materials.
