Abstract In this paper, a carbon nanofiber (CNF) hybrid nanomaterial composed of MnO-Sn cubes embedding in nitrogen-doped CNF (MnO-Sn@CNF) is synthesized through electrospinning and post-thermal reduction processes. It exhibits good electrochemical lithium-ion storage performance as anode, such as high reversible capacity, outstanding cycle performance (754 mAh g-1 at 1 A/g after 1000 cycles), and good rate capability (447 mAh g-1 at 5A/g). The excellent electrochemical properties are derived from unique nanostructure design. MnO-Sn@CNF has a three-dimensional (3D) conductive network with a stable core-shell structure, which improves the electrical conductivity and mechanical stability of the materials. In addition, the mesopores on the surface of carbon fibers can shorten the diffusion distance of lithium ions and promote the combination of active sites of the material with lithium ions. The internal MnO and Sn form a heterostructure, which enhances the stability of the physical structure of the electrode material. This material design method provides a reference strategy for the development of high-performance lithium-ion batteries anode.
