Abstract

Cu₂Nb₃₄O₈₇ with an inverse opal morphology is fabricated, showing highly-ordered macropores with sizes of ∼170 nm and walls with thicknesses of 20-30 nm. This first-reported Cu₂Nb₃₄O₈₇ nanomaterial exhibits good Li⁺-storage properties, including a large capacity, safe operating potential, large initial coulombic efficiency, high rate performance and good cycling stability.
