Micronano Porous Mo2C@C Nanorods Composites as Robust Anodes for Li‐ion Battery

Micronano porous Mo 2 C@C nanorods (NRs) composite anodes are successfully synthesized using the raw materials of MoO 3 NRs, polyacrylonitrile (PAN) polymer, and inactive sodium chloride (NaCl) microparticles. The abundant and soluble NaCl microparticles act as the sacrificial templates, which increase the surface contact area between the MoO 3 NRs and the PAN polymer, thus promoting the thorough formation of Mo 2 C electrodes during the carbonization process. The optimized Mo 2 C@C‐template (MCC‐T) NR composite electrodes deliver an enhanced electrochemical performance, which is ascribed to the enlarged surface area, reduced path distance of lithium ions, and structural stability. In addition, the Li‐ion storage mechanism and the electrochemical kinetics of Mo 2 C@C NR composite anodes are also systemically and experimentally investigated by ex situ X‐ray diffraction (XRD) and cyclic voltammetry (CV) techniques. This synthetic strategy for MCC‐T NR composite anodes is helpful to design other nanostructured carbide anodes for high‐performance lithium‐ion batteries (LIBs).
