Sol–gel synthesis of <i>Dictyophora</i>-shaped hierarchically porous Mn₂SnO₄/C materials as anodes for Li-ion batteries

Abstract

Dictyophora-shaped porous Mn₂SnO₄/C composite materials were prepared by a sol–gel process accompanied by phase separation. The samples possess a well-defined interconnected micro–meso–macroporous structure which benefits the cycling performance for Li-ion batteries.
