Two-dimensional Nb2O5 holey nanosheets prepared by a graphene sacrificial template method for high performance Mg2+/Li+ hybrid ion batteries

Abstract

Mg2+/Li+ hybrid ion batteries (MLIBs) are regarded as a promising candidate for electrical energy devices due to the combination of fast lithium intercalation cathode and safe magnesium anode. Herein, the two-dimensional Nb2O5 holey nanosheets are synthesized by a graphene oxide sacrificial template method and used as the cathode of MLIBs for the first time. It exhibits a high discharge capacity (195.9 mAh g−1 at 100 mA g−1), excellent rate performance (72.1 mAh g−1 at 2000 mA g−1) and long cycling life (capacity fading rate of 0.032 % per cycle at 2000 mA g−1 over 1000 cycles). The remarkable electrochemical performance could be attributed to the unique two-dimensional holey nanosheets structure, which is beneficial for improving electronic conductivity and lithium ion conductivity.
