▎ 摘　　要

Porous structures in anode materials are of importance to accommodate volume dilation of active matters. In the present case, a carbon nanoporous framework is hydrothermally synthesized from glucose in the presence of graphene oxide, together with in situ active Fe3O4 nanoparticles within it. The composite anode material has outstanding electrochemical performance, including high specific capacity, excellent cyclic stability, and superior rate capability. The specific capacity stays at 830.8 mA h g(-1) after 200 cycles at 1 A/g, equivalent to a high-capacity retention of 88.7%. The findings provide valuable clues to tailor morphology of hydrothermally carbonized glucose for advanced composite anode materials of lithium-ion batteries.
