With the advent of flexible electronics, lithium-ion batteries have become a key component of high performance energy storage systems. Thus, considerable effort is made to keep up with the development of flexible lithium-ion batteries. To date, many researchers have studied newly designed batteries with flexibility, however, there are several significant challenges that need to be overcome, such as degradation of electrodes under external load, poor battery performance, and complicated cell preparation procedures. In addition, an in-depth understanding of the current challenges for flexible batteries is rarely addressed in a systematical and practical way. Herein, recent progress and current issues of flexible lithium-ion batteries in terms of battery materials and cell designs are reviewed. A critical overview of important issues and challenges for the practical application of flexible lithium-ion batteries is also provided. Finally, the strategies are discussed to overcome current limitations of the practical use of flexible lithium-based batteries, providing a direction for future research.
随着柔性电子技术的出现，锂离子电池已成为高性能储能系统的关键组件。因此，人们付出了巨大努力以跟上柔性锂离子电池的发展步伐。迄今为止，许多研究人员已对具有柔性的新型电池进行了研究，然而，仍有几个重大挑战需要克服，例如外部负载下电极的退化、电池性能不佳以及复杂的电池制备工艺。此外，很少有研究以系统且实用的方式深入探讨柔性电池当前面临的挑战。在此，本文综述了柔性锂离子电池在电池材料和电池设计方面的最新进展及当前问题。还对柔性锂离子电池实际应用中的重要问题和挑战进行了批判性概述。最后，讨论了克服柔性锂基电池实际应用中当前限制的策略，为未来研究提供了方向。
