## Description

- description: Mn-based transition metal oxides nanoparticles are promising candidates
    as cathode active materials for rechargeable magnesium batteries, but their high
    catalytic activity for oxidative electrolyte decomposition and large surface area
    deteriorate their cycle performance. A recent study [Yagi et al. J. Mater. Chem.
    A, 2021, 9, 26401–26409] demonstrated that the catalytic activity was less prominent
    in Fe-based oxides than in other transition metal oxides, containing Mn. Fe-based
    oxides show low catalytic activity for oxidative electrolyte decomposition compared
    with Mn-based congeners. The strong capability of oxalate ions for bridging transition
    metal ions was utilised to form thin, uniform Fe2O3 layers on nanoparticles of
    MgMn2O4 and -MnO2. The resulting Fe2O3 layers effectively suppressed side reactions
    during insertion and extraction of the Mg2+ ions and improved the capacity retention
    and cycle performance.
