Electrolyte Uptake

Cellulose nanofibrils (CNF) with high thermal stability and excellent electrolyte wettability attracted tremendous attention as a promising separator for the emerging sodium-ion batteries. The pore structure of the separator plays a vital role in electrochemical performance. CNF separators are assembled using the bottom-up approach in this study, and the pore structure is carefully controlled through film-forming techniques. The acid-treated separators prepared from the solvent exchange and freeze-drying demonstrated an optimal pore structure with a high electrolyte uptake rate (978.8%) and Na+ transference number (0.88). Consequently, the obtained separator showed a reversible specific capacity of 320 mAh/g and enhanced cycling performance at high rates compared to the commercial glass fiber separator (290 mAh/g). The results highlight that CNF separators with an optimized pore structure are advisable for sodium-ion batteries.

The effects of fluorine (F) doping on the phase, crystal structure, and electrochemical performance of Na2Ti3O7 are studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and electrochemical measurements. F-doping does not change the crystal structure of NTO, although it has an effect on the morphology of the resultant product. As an anode material for sodium-ion batteries, the specific capacity of Na2Ti3O7 exhibits a 30% increase with F-doping owing to the improved sodium ion diffusion coefficient. F-doped Na2Ti3O7 also displays an enhanced rate capability and favourable cycling performance for more than 800 cycles.

Nanofiber Mats

Transition metal oxides applied as anode material for sodium-ion batteries have been widely investigated due to their high specific capacity, especially for Co3O4-related nanomaterials. However, its intrinsic low electronic conductivity and the aggregation phenomenon of commercial Co3O4 nanoparticles result in a low initially coulombic efficiency and the fading of cycle performance. In this paper, commercial Co3O4 nanoparticles/carbon composite nanofiber mats were synthesized by sol–gel electrospinning. When directly applied, such flexible negative electrodes as sodium-ion batteries, revealed high specific capacity and excellent rate performance simultaneously, which are not only attributed to the high electronic conductivity of carbon nanofiber mats that could enhance the ionic and electronic transport property, but also attributed to its three-dimensional fibrous network that could prevent the aggregation of commercial Co3O4 nanoparticles. Such a flexible, binder-free and high electronic conductivity negative electrode enables promising applications for large-scale energy storage and conversion.
