Sodium-ion batteries (SIBs) have attracted wide attention from academia and industry due to the low cost and abundant sodium resources. Despite the rapid industrialization development of SIBs, it still faces problems such as a low initial coulombic efficiency (ICE) leading to a significant decrease in battery energy density (., 20%). Sodium compensation technology (SCT) has emerged as a promising strategy to effectively increase the ICE to 100% and drastically boost battery cycling performance. In this review, we emphasize the importance of SCT in high-performance SIBs and introduce its working principle. The up-to-date advances in different SCTs are underlined in this review. In addition, we elaborate the current merits and demerits of different SCTs. This review also provides insights into possible future research directions in SCT for high-energy SIBs.
钠离子电池(SIBs)因其低成本和丰富的钠资源而受到学术界和工业界的广泛关注。尽管钠离子电池实现了快速的工业化发展,但它仍然面临着诸如初始库仑效率(ICE)较低导致电池能量密度显著下降(例如,下降20%)等问题。钠补偿技术(SCT)已成为一种有前景的策略,可有效将初始库仑效率提高到100%,并大幅提升电池的循环性能。在本综述中,我们强调了钠补偿技术在高性能钠离子电池中的重要性,并介绍了其工作原理。本综述着重介绍了不同钠补偿技术的最新进展。此外,我们阐述了不同钠补偿技术目前的优缺点。本综述还对高能量钠离子电池钠补偿技术未来可能的研究方向提供了见解。
