Article Synopsis
- Commercial lithium-ion batteries are nearing their maximum energy capacity, falling short of increasing storage needs, which has led to interest in lithium-sulfur (Li-S) batteries due to their superior energy capacity and density.
- Li-S batteries face hurdles like poor conductivity, expansion of sulfur, and the shuttle effect, which affect their practical use.
- Electrospun carbon-based nanofibers are proposed as a solution, offering unique structural benefits and flexibility, and this review discusses their role in enhancing Li-S battery performance while addressing current challenges and future prospects.
Lithium-sulfur (Li-S) batteries are promising candidates for next-generation energy storage. However, the notorious lithium polysulfides (LiPSs) shuttle effect and torpid redox kinetics hinder their practical application. Enhancing phase conversion efficiency and limiting the dissolution of LiPSs are critical for stabilizing Li-S batteries.

- Porous carbon nanofibers (CACNFs) are created by carbonizing and activating cellulose acetate (CA) nanofibers in a single step, enhancing their thermal stability and surface properties through ZnCl coating.
- * The characteristics of CACNFs were significantly affected by the concentration of the dipping solution, which improved their morphology, crystal structure, and specific surface area.
- * CACNFs exhibited impressive electrochemical properties as supercapacitor electrodes, with high specific capacitance and excellent stability over many cycles, indicating their potential for energy storage applications.*
