However, low mechanical strength of carbon matrix is incapable of maintaining structural stability and electron/ion conductivity of Si anodes. Herein, we employ electrospinning-carbonization to construct free-standing Si@carbon nanofibers with internal ordered channels, uniformly distributed Si nanoparticles, and extraordinary elastic modulus (0.22 GPa) by introducing polystyrene (PS) as an oriented filler. The free-standing and rigid-flexible ordered multichannel carbon nanofibers (OM-CNFs) can absorb the volume variation of Si, effectively enhancing the mechanical strength and chemical stability of electrodes. The Si NPs uniformly embedded into highly conductive OM-CNFs matrix establishes a bicontinuous structure and increases the contact area between Si and CNFs, thus boosting the rate capability. Consequently, the Si@OM-CNFs anode delivers an excellent reversible capacity of 939.9 mA h g -1 even at a high current density of 5 A g -1 after 300 cycles. The assembled full-cell with prelithiated Si@OM-CNFs anode and LiFePO 4 cathode delivers a reversible capacity of 104 mA h g -1 at 85 mA g -1 , corresponding to a high energy density of 341 Wh kg -1 . This work provides insights into the design of high mechanical strength Si/C composite anodes for high-performance LIBs.
