Abstract

Zinc-ion batteries (ZIBs) are emerged as a promising alternative for sustainable energy storage, offering advantages such as safety, low cost, and environmental friendliness. However, conventional aqueous electrolytes in ZIBs face significant challenges, including hydrogen evolution reaction (HER) and zinc dendrite formation, compromising their cycling stability and safety. These limitations necessitate innovative electrolyte solutions to enhance ZIB performance while maintaining sustainability. This review explores the potential of natural solvent-based electrolytes derived from renewable and biodegradable resources. Natural deep eutectic solvents (DES), bio-ionic liquids, and biomass-derived organic compounds present unique advantages, including a wider electrochemical stability window, reduced HER activity, and controlled zinc deposition. Examples include DESs based on choline chloride (ChCl), glycerol-based systems, and biomass-derived solvents such as γ-valerolactone (GVL) and aloe vera, demonstrating improved cycling stability and dendrite suppression. Despite their promise, challenges such as high viscosity, cost, and scalability remain critical barriers to commercialization. This review underscores the need for further research to optimize natural solvent formulations, enhance Zn anode compatibility, and integrate these systems into practical applications. By addressing these challenges, natural solvent-based electrolytes can pave the way for safer, high-performance, and environmentally sustainable ZIBs, particularly large-scale energy storage systems.

走向绿色和可持续的锌离子电池：天然溶剂型电解质的潜力

锌离子电池（zib）具有安全、低成本、环保等优点，是一种很有前途的可持续能源存储替代方案。然而，传统的水电解质在ZIBs中面临着巨大的挑战，包括析氢反应（HER）和锌枝晶的形成，影响了它们的循环稳定性和安全性。这些限制需要创新的电解质解决方案来提高ZIB的性能，同时保持可持续性。本文综述了从可再生和可生物降解资源中提取的天然溶剂基电解质的潜力。天然深共晶溶剂（DES）、生物离子液体和生物质衍生的有机化合物具有独特的优势，包括更宽的电化学稳定窗口、更低的HER活性和可控的锌沉积。例如，基于氯化胆碱（ChCl）、甘油体系和生物质衍生溶剂（如γ-戊内酯（GVL）和芦荟）的DESs，显示出更好的循环稳定性和枝晶抑制能力。尽管前景看好，但高粘度、高成本和可扩展性等挑战仍然是商业化的关键障碍。本综述强调需要进一步研究以优化天然溶剂配方，增强锌阳极相容性，并将这些系统整合到实际应用中。通过解决这些挑战，天然溶剂型电解质可以为更安全、高性能和环境可持续的zib铺平道路，特别是大型储能系统。
