Abstract

Aqueous alkali metal-ion batteries (AAMIBs) have been recognized as emerging electrochemical energy storage technologies for grid-scale applications owning to their intrinsic safety, cost-effectiveness, and environmental sustainability. However, the practical application of AAMIBs is still severely constrained by the tendency of aqueous electrolytes to freeze at low temperatures and decompose at high temperatures, limiting their operational temperature range. Considering the urgent need for energy systems with higher adaptability and resilience at various application scenarios, designing novel electrolytes via structure modulation has increasingly emerged as a feasible and economical strategy for the performance optimization of wide-temperature AAMIBs. In this review, the latest advancement of wide-temperature electrolytes for AAMIBs is systematically and comprehensively summarized. Specifically, the key challenges, failure mechanisms, correlations between hydrogen bond behaviors and physicochemical properties, and thermodynamic and kinetic interpretations in aqueous electrolytes are discussed firstly. Additionally, we offer forward-looking insights and innovative design principles for developing aqueous electrolytes capable of operating across a broad temperature range. This review is expected to provide some guidance and reference for the rational design and regulation of wide-temperature electrolytes for AAMIBs and promote their future development.

碱金属离子电池用宽温电解质：挑战、进展与展望

由于其固有的安全性、成本效益和环境可持续性，水基碱金属离子电池（aamib）已被公认为电网规模应用的新兴电化学储能技术。然而，aamib的实际应用仍然受到水电解质在低温下冻结和高温下分解的趋势的严重制约，限制了它们的工作温度范围。考虑到在各种应用场景下对具有更高适应性和弹性的能源系统的迫切需求，通过结构调制设计新型电解质已日益成为一种可行且经济的宽温aamib性能优化策略。本文系统、全面地综述了aamib宽温电解液的最新研究进展。具体来说，首先讨论了关键挑战，失效机制，氢键行为与物理化学性质之间的关系，以及水电解质的热力学和动力学解释。此外，我们为开发能够在广泛温度范围内工作的水性电解质提供前瞻性的见解和创新的设计原则。希望对aamib宽温电解液的合理设计和调控提供一定的指导和参考，促进其未来的发展。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
