Reconstruction of Mini‐Hollow Polyhedron Mn₂O₃ Derived from MOFs as a High‐Performance Lithium Anode Material

Abstract

<b>A mini-hollow polyhedron Mn₂O₃</b><b>is used as the anode material</b> for lithium-ion batteries. Benefiting from the small interior cavity and intrinsic nanosize effect, a stable reconstructed hierarchical nanostructure is formed. It has excellent energy storage properties, exhibiting a capacity of 760 mAh g^-1 at 2 A g^-1 after 1000 cycles. This finding offers a new perspective for the design of electrodes with large energy storage.
