Novel ZnMoO4/reduced graphene oxide hybrid as a high-performance anode material for lithium ion batteries

Herein, a novel ZnMoO4/reduced graphene oxide (rGO) hybrid was synthesized via a one-pot hydrothermal method followed by a thermal annealing process for the first time. The plate-like ZnMoO4 with diameter of 50-200 nm were uniformly distributed on the basal plane of two-dimensional rGO. As a novel anode material, ZnMoO4/rGO hybrid exhibited high reversible capacity (maximum capacity of 923.4 mAh g−1 at 0.1 A g−1), good rate capability (354.1 mAh g−1 at 2 A g−1), and excellent cycling stability over 500 cycles (0.064% capacity loss per cycle) overwhelmingly superior to those of bare ZnMoO4-based anode. The enhanced electrochemical performance of ZnMoO4/rGO hybrid is due to the unique composite structure with improved electronic conductivity, shortened lithium ion transport pathways, decreased lithium ions diffusion resistance, and the synergistic effect between the crystalline ZnMoO4 and the conductive rGO matrix.
