## Description

- description: we fabricate an ultraporous (>500 m2 g−1) and ultrasmall (<2.5 nm)
    cubic spinel MgMn2O4 (MMO) by a freeze-dry assisted room-temperature alcohol reduction
    process. While the as fabricated MMO exhibits a discharge capacity of 160 mAh
    g−1, the removal of its surface hydroxy groups by heat-treatment activates it
    without structural change, improving its discharge capacity to 270 mAh g−1, the
    theoretical capacity at room temperature. These results are made possible by the
    ultraporous, ultrasmall particles that stabilize the metastable cubic spinel phase,
    promoting both the Mg2+ insertion/deintercalation in the MMO and the reversible
    transformation between the cubic spinel and cubic rock-salt phases.
