摘要

钠离子电池(SIBs)由于其高资源丰度和低成本而成为下一代电化学储能系统的有力候选者。然而,传统的sib依赖于易燃的有机液体电解质(LEs),在滥用条件下容易发生电池火灾和爆炸,阻碍了sib的广泛应用。电池安全事故的频繁发生与电解质的性质密切相关,这也推动了不燃电解质的发展。本文综述了sib用不燃电解质的最新进展。首先,对sib的电解质体系进行了简要概述。然后,全面探讨了不可燃溶剂和阻燃溶剂的阻燃机理,为不可燃电解质的设计提供了指导。然后,回顾了不可燃LEs的发展,包括有机不可燃电解质、水性电解质和离子液体电解质。对于非可燃固态电解质,我们总结了无机固态电解质、聚合物固态电解质和复合固态电解质的特点。最后,强调了不可燃电解质在sib中的重要性,并概述了下一代本质安全sib的潜在研究方向和仍然存在的挑战。这一综述为促进先进sib的发展提供了有价值的科学和实践参考。

Non-flammable electrolytes for high-safety sodium-ion batteries

Non-flammable electrolytes for high-safety sodium-ion batteries
Sodium-ion batteries (SIBs) have emerged as strong candidates for next-generation electrochemical energy storage systems due to their high resource abundance and low cost. However, traditional SIBs rely on flammable organic liquid electrolytes (LEs), which are prone to battery fires and explosions under abusive conditions, hindering the wide application of SIBs. The frequent occurrence of battery safety incidents is closely related to the properties of the electrolytes, which has driven the development of non-flammable electrolytes. This review summarizes the recent developments in non-flammable electrolytes for SIBs. Firstly, the electrolyte system of SIBs is briefly summarized. Then, a comprehensive discussion of the flame-retardant mechanisms of non-flammable and flame-retardant solvents to guide the design of non-flammable electrolytes is provided. Afterward, the development of non-flammable LEs is reviewed, including organic non-flammable electrolytes, aqueous electrolytes, and ionic liquid electrolytes. For non-flammable solid-state electrolytes, we summarize the characteristics of inorganic solid-state electrolytes, polymer solid-state electrolytes, and composite solid-state electrolytes. Lastly, the critical importance of non-flammable electrolytes in SIBs is underscored and the potential research directions and remaining challenges for the next generation of intrinsically safe SIBs are outlined. This review offers a valuable reference for scientific and practical issues to promote the development of advanced SIBs.
