Summary: Sodium and potassium ion storage has gained more attention recently due to their competitive cost-benefit and sustainable resource supply. Maintaining a stable electrode structure during the electrochemical process for the larger radius ions of Na+ and K+ is challenging. 1D materials, as electrodes, offer insights into the relationship between physical-chemical properties and dimension, and provide convenient migration pathways for electrons or ions, enhancing charge transfer and reducing contact resistance. Electrospinning, as a controllable and facile synthesis approach, can be used to design 1D nanofibers with tunable compositions and morphologies to achieve high electrochemical activity and stability. This review discusses current electrospun techniques for stable electrodes and enhanced electrochemical stability for larger radius ions, and includes approaches to improve the thermal stability and mechanical strength of separators through electrospinning strategies.
