## Description

- description: Rechargeable magnesium battery (RMB) is gaining attention as promising
    alternatives to lithium-ion batteries, offering advantages such as low cost and
    high theoretical capacity of magnesium metal anodes. Yet, realizing stable, high-voltage
    RMB full cells remains a considerable challenge. In this study, we explore a full-cell
    configuration combining a vanadium oxide (VO2) cathode with a weakly coordinating
    anion-based electrolyte. While encouraging performance is observed in half-cell
    setups, translating it into full-cell operation proves complex, particularly at
    elevated temperatures. At 60 °C, the initial discharge capacity of 77 mAh g−1
    decreases notably to 28 mAh g−1 in the second cycle, whereas performance at 30 °C
    remains more stable around 25 mAh g−1. Three-electrode measurement suggests increasing
    overpotentials at the Mg anode as a key factor in the capacity degradation. Further
    analysis points to issues such as uneven Mg plating/stripping, surface pitting,
    and minor vanadium dissolution, contributing to impedance growth and cross-over
    effects. These are linked to cathode–electrolyte side reactions, particularly
    under high voltage. Overall, the results emphasize the importance of developing
    stable interphases to enhance the long-term performance of RMB full cells especially
    at elevated temperature.
