Rapidly developed Na-ion batteries are highly attractive for grid energy storage. Nevertheless, the safety issues of Na-ion batteries are still a bottleneck for large-scale applications. Similar to Li-ion batteries (LIBs), the safety of Na-ion batteries is considered to be tightly associated with the electrolyte and electrode/electrolyte interphase. Although the knowledge obtained from LIBs is helpful, designing safe electrolytes and obtaining stable interphases in Na-ion batteries is still a huge challenge. Therefore, it is of significance to investigate the key factors and develop new strategies for the development of high-safety Na-ion batteries. This comprehensive review introduces the recent efforts from nonaqueous electrolytes and interphase aspects of Na-ion batteries, proposes their design strategies and requirements for improving safety characteristics, and discusses the potential issues for practical applications. The insight to formulate safe electrolytes and design the stable interphase for Na-ion batteries with high safety is intended to be provided herein.
快速发展的钠离子电池在电网储能方面极具吸引力。然而，钠离子电池的安全问题仍是其大规模应用的瓶颈。与锂离子电池（LIBs）类似，钠离子电池的安全性被认为与电解质以及电极/电解质界面紧密相关。尽管从锂离子电池中获得的知识有所帮助，但设计安全的电解质并在钠离子电池中获得稳定的界面仍然是一个巨大的挑战。因此，研究高安全性钠离子电池发展的关键因素并制定新策略具有重要意义。这篇综述介绍了钠离子电池非水电解质和界面方面的最新研究成果，提出了提高安全特性的设计策略和要求，并讨论了实际应用中的潜在问题。本文旨在提供关于为高安全性钠离子电池配制安全电解质和设计稳定界面的见解。
