摘要
柔性锌离子电池(FZIB)的发展在很大程度上取决于凝胶电解质的开发,凝胶电解质具有机械性能、离子导电性和环保生产工艺等特点。这一领域面临的主要挑战是设计出一种凝胶电解质,它能有效封装所有这些关键属性,以实现实际应用。本研究介绍了一种为 FZIB 开发的新型锌离子凝胶(Zn-gel)电解质,它是通过乙醇蒸汽诱导纤维素分子组装合成的。这种创新工艺促进了与 Zn2+ 离子的氢键和离子络合,从而使凝胶具有超强的机械强度(0.88 兆帕)、高离子转移率(超过 0.7)和惊人的离子电导率(8.39 mS cm-1)。在不使用液态电解质的情况下,锌凝胶使 FZIB 在 500 次循环后达到 207.3 mAh g-1 的可逆容量和 93% 以上的库仑效率。这项研究为高性能、环保型凝胶电解质开辟了一条前景广阔的途径,推动了柔性电子器件和便携式设备的应用,展示了生物基聚合物在提高储能技术方面的巨大潜力。
Ethanol Vapor-Induced Synthesis of Robust, High-Efficiency Zinc Ion Gel Electrolytes for Flexible Zn-Ion Batteries
The evolution of flexible Zn-ion batteries (FZIBs) significantly hinges on the development of gel electrolytes, characterized by their mechanical properties, ionic conductivity, and environmentally friendly production processes. The prevailing challenge in this domain has been devising a gel electrolyte that encapsulates all these critical attributes effectively for practical application. This study presents a novel zinc ion gel (Zn-gel) electrolyte developed for FZIBs, synthesized via ethanol vapor-induced assembly of cellulose molecules. This innovative process fosters significant hydrogen bonding and ion-complexation with Zn2+ ions, resulting in a gel with exceptional mechanical strength (0.88 MPa), high ion transference (over 0.7), and impressive ionic conductivity (8.39 mS cm−1). The Zn-gel enables a FZIB to achieve a reversible capacity of 207.3 mAh g−1 and over 93% Coulombic efficiency after 500 cycles, devoid of liquid electrolyte. Highlighting a promising route for high-performance, eco-friendly gel electrolytes, this research advances flexible electronics and portable device applications, demonstrating the profound potential of bio-based polymers in enhancing energy storage technology.
