摘要
锌碘水溶液(Zn-I2)电池作为一种新兴的氧化还原转换储能系统,以其低成本和高安全性吸引了广泛的研究兴趣。然而,由于氧化还原转化不完全和锌阳极表面锌镀层不均匀而产生的多碘化物穿梭效应始终阻碍着锌碘电池的商业应用。在这项工作中,报告了一种针对长寿命 Zn-I2 电池的 "一石二鸟 "策略。根据这一策略,磺酸盐功能化碳纤维不仅可以作为出色的碘限制器抑制碘物种的穿梭,还可以作为锌阳极表面的均匀镀锌引导层防止 Zn2+ 的不均匀沉积。因此,这种电池具有出色的循环稳定性(在 5 A g-1 条件下循环 10,000 次后,容量为 124 mAh g-1)。理论计算表明,磺酸盐基团成功地诱导了碳基底上的电荷再分布,从而加强了碘物种与碳基底的电子相互作用。电荷富集的磺酸盐基团可通过与 Zn2+ 的强烈库仑效应引导 Zn2+ 均匀沉积。这项研究为充电电池阴极和阳极的一体化设计提供了新的视角。
Sulfonate-functionalization in Zn-iodine batteries as one stone kills two birds: iodine limiter and uniform Zn plating guidance layer
Aqueous Zn-iodine (Zn-I2) batteries have attracted extensive research interest as an emerging redox conversion energy storage system due to the low cost and high safety. However, the shuttling effects of polyiodides arising from incomplete redox conversion and inhomogeneous Zn plating on the Zn anode surface always hinder the commercial application of Zn-I2 batteries. In this work, a two-birds-with-one-stone strategy is reported for long-life Zn-I2 batteries. Based on the strategy, the sulfonate-functionalized carbon fiber not only acts as the excellent iodine limiter to inhibit iodine species shuttling, but also as the uniform Zn plating guidance layer on the Zn anode surface to prevent the inhomogeneous deposition of Zn2+. Consequently, a superior cycling stability (a capacity of 124 mAh g−1 after 10,000 cycles at 5 A g−1) is achieved. Theoretical calculations illustrate that sulfonate groups successfully induce charge redistribution on the carbon substrate, thereby strengthening the electronic interactions of the iodine species with the carbon substrate. The charge-enriched sulfonate groups can guide the uniform deposition of Zn2+ through a strong Coulombic effect with Zn2+. This work gives a new perspective on the integrated design of cathodes and anodes for rechargeable batteries.
