| Summary: | 2-D transition metal carbides (TMCs)-based anode materials offer competitive performance in lithium-ion batteries (LIBs) owing to its excellent conductivity; cheaper, flexible uses; and superior mechanical stability. However, the electrochemical energy storage of TMCs is still the major obstacle due to their modest capacity and the trends of restacking/aggregation. In this report, the Mo<sub>2</sub>C nanosheets were attached on conductive CNT network to form a hierarchical 2D hybrid structure, which not only alleviated the aggregation of the Mo<sub>2</sub>C nanoparticle and facilitated the rapid transference of ion/electron, but also adapted effectually to the hefty volume expansion of Mo<sub>2</sub>C nanosheets and prevented restacking/collapse of Mo<sub>2</sub>C structure. Benefitting from the layered Mo<sub>2</sub>@CNT hybrid structure, the charge/discharge profile produced a 200 mAh g<sup>−1</sup> discharge-specific capacity (second cycle) and 132 mAh g<sup>−1</sup> reversible-discharge discharge-specific capacity (after 100 cycles) at 50 mA g<sup>−1</sup> current density, with high-speed competency and superior cycle stability. The improved storage kinetics for Mo<sub>2</sub>@CNT hybrid structure are credited to the creation of numerous active catalytic facets and association reaction between the CNT and Mo<sub>2</sub>C, promoting the efficient electron transfer and enhancing the cycling stability.
