Nanoengineering of electrode materials can directly facilitate sodium ion accessibility and transport, thus enhancing electrochemical performance in sodium ion batteries. Here, highly sodium-accessible carbon coated nanoporous TiO2 microfibers have been synthesised via the facile electrospinning technique which can deliver an enhanced capacity of approximate to 167 mAh g(-1) after 450 cycles at current density of 50 mA g(-1) and retain a capacity of approximate to 71 mAh g(-1) at the high current rate of 1 A g(-1). With the benefits of their porous structure, thin TiO2 inner walls, and the introduction of conductive carbon, the nanoporous TiO2/C microfibers exhibit high ion accessibility, fast Na ion transport, and fast electron transport, thereby leading to the excellent Na-storage properties presented here. Nanostructuring is proven to be a fruitful strategy that can alleviate the reliance on materials' intrinsic nature; and the electrospinning technique is versatile and cost-effective for the fabrication of such an effective nanoporous microfiber structure.
