摘要：

钠碘（Na-I）电池作为一种潜在的可替代锂离子电池的储能装置，展现出良好的发展前景。然而，其实际应用受到导电性差、热稳定性不足以及多碘化物溶解与穿梭效应的限制。在本研究中，我们报道了一种通过碳化商用三聚氰胺海绵制备碳海绵（MC）的新方法。所制备的MC具有独特的自生长碳纳米管结构，能够为多碘化物提供物理和化学吸附，从而有效改善Na-I2电池的电化学性能。实验结果表明，NaI/MC电极大幅降低了电化学阻抗，并减少了多碘化物的溶解效应。NaI/MC正极在200次循环测试中平均放电容量为92.75 mAh·g^-1，同时库仑效率稳定维持在94%。本研究成果展示了在储能钠离子电池领域潜在的应用前景。

Abstract:

The sodium-iodine (Na-I) battery exhibits significant potential as an alternative energy storage device to the lithium-ion battery. However, its development is hindered by inadequate electrical and thermal stability, as well as the dissolution and shuttling of polyiodide. In this study, we report a preparation method for melamine carbon sponge (MC) via carbonizing a commercially available kitchen sponge. It was revealed that the as-prepared MC, composed of unique self-growing carbon nanotubes, could provide both physical and chemical adsorption capabilities for intermediate polyiodides to improve the electrochemical performance of NaI. Consequently, the NaI/MC electrode effectively minimized polyiodide dissolution and reduced the electrochemical impedance. The NaI/MC cathode demonstrated a high average discharge capacity of 92.75 mAh·g^-1 over 200 cycles while maintaining a coulombic efficiency of 94%. The research findings from our study have promising applications in Na-I batteries.
