Effective 3D open-channel nanostructures of a MgMn₂O₄ positive electrode for rechargeable Mg batteries operated at room temperature

Abstract

Room-temperature operations of rechargeable Mg coin-cell batteries have been achieved using a spinel MgMn₂O₄ powder having a large specific surface area > 200 m² g^–1 and more than 90% porosity with a triple-tiered 3D open-channel network.
