The construction of a complex structure and component adjustment are effective strategies for improving voLume expansion and conductivity of transition metal oxides, which serve as promising anode materials in Lithium-ion batteries with high capacity. Herein, a facile metal-organic framework-engaged strategy was demonstrated for the synthesis of hierarchical porous CoMoO4-CoO/S@rGO nano polyhedrons via hydrothermal S doping. The improvement of S doping originated from enlarged interplanar spacing, enhanced conductivity, and increased pseudocapacitance contribution. Meanwhile, the porous structure relieved voLume expansion during the LithiationideLithiation processes and exposed more active sites of Li storage. The CoMoO4-CoO/S@rGO electrode exhibited ultrahigh specific capacity (1103 mA h g(-1) at 0.5 A g(-1)) and excellent rate capacity (652 mA h g(-1) at 5 A g(-1)). This work indicated that the rational structural design and insights into anionic doping have guiding significance for other metal oxides with high capacity and high-rate capability.
