高性能柔性电源已经引起了人们的关注，因为它们能够实现下一代可弯曲、可植入和可穿戴电子系统。尽管可再充电锂离子电池（LIB）已被视为高性能柔性能源的强有力候选者，但用于可弯曲LIB的顺应性电极仅限于少数材料，并且它们的性能不足以使它们应用于包括可卷曲显示器的柔性消费电子产品。在本文中，我们提出了一种灵活的薄膜锂离子电池开发使用的通用转移方法，使不同的灵活的锂离子电池的实现，无论电极化学。此外，它可以在聚合物基板上形成高温（HT）退火电极，用于高性能LIB。然后将可弯曲的LIB与柔性发光二极管（LED）集成，从而形成一体化的柔性电子系统。通过有限元分析（FEA）模拟，探索并充分支持出色的电池性能。
High-performance flexible power sources have gained attention, as they enable the realization of next-generation bendable, implantable, and wearable electronic systems. Although the rechargeable lithium-ion battery (LIB) has been regarded as a strong candidate for a high-performance flexible energy source, compliant electrodes for bendable LIBs are restricted to only a few materials, and their performance has not been sufficient for them to be applied to flexible consumer electronics including rollable displays. In this paper, we present a flexible thin-film LIB developed using the universal transfer approach, which enables the realization of diverse flexible LIBs regardless of electrode chemistry. Moreover, it can form high-temperature (HT) annealed electrodes on polymer substrates for high-performance LIBs. The bendable LIB is then integrated with a flexible light-emitting diode (LED), which makes an all-in-one flexible electronic system. The outstanding battery performance is explored and well supported by finite element analysis (FEA) simulation.
