Abstract

The increasing demand for high-performance lithium-ion batteries (LIBs) in portable electronics and electric vehicles has driven extensive research into advanced electrolytes. Ionic liquids (ILs) and their derived electrolytes, including poly(ionic liquids), ionogels, and IL-functionalized systems, provide significant potential for enhancing the safety and electrochemical performance of LIBs due to their unique properties, such as non-volatility, wide electrochemical windows, and excellent thermal stability. These properties enable safer, high-energy, and long-lasting batteries. In order to benchmark the important development of the new concepts and technologies emerging in IL-based electrolytes, this review conducts a thorough analysis of the physicochemical properties of ILs and their versatile applications in electrolytes, particularly emphasizing their adaptability to fulfill the specific needs of different battery systems. In liquid electrolyte systems, ILs can function as solvents, interfacial modifiers, and critical components for constructing artificial solid electrolyte interphase (SEI). In (quasi-)solid-state electrolyte systems, ILs can be polymerized to form poly(ionic liquid)s or integrated with organic, inorganic, or composite materials to develop IL-based electrolytes, demonstrating multifunctional electrochemical performance. Finally, the review critically examines the challenges and opportunities in this field, offering insightful perspectives for future advancements.

离子液体电解质的合理工程:向先进锂电池的革命性范式转变
便携式电子产品和电动汽车对高性能锂离子电池(lib)的需求不断增长,推动了对先进电解质的广泛研究。离子液体及其衍生电解质,包括聚离子液体、离子凝胶和离子功能化体系,由于其独特的性质,如无挥发性、宽电化学窗口和优异的热稳定性,为提高离子液体的安全性和电化学性能提供了巨大的潜力。这些特性使电池更安全、高能量、更持久。为了对基于il的电解质的新概念和新技术的重要发展进行基准,本文对il的物理化学性质及其在电解质中的广泛应用进行了深入的分析,特别强调了它们的适应性,以满足不同电池系统的特定需求。在液体电解质体系中,il可以作为溶剂、界面改性剂和构建人工固体电解质界面相(SEI)的关键组分。在(准)固态电解质体系中,il可以聚合形成多离子液体,也可以与有机、无机或复合材料结合形成il基电解质,展示多功能电化学性能。最后,本文批判性地审视了该领域的挑战和机遇,为未来的发展提供了有见地的观点。
