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.
高性能柔性电源受到了广泛关注，因为它们能够实现下一代可弯曲、可植入和可穿戴的电子系统。尽管可充电锂离子电池（LIB）已被视为高性能柔性能源的有力候选者，但可弯曲 LIB 的兼容电极仅限于少数几种材料，其性能还不足以将其应用于包括可卷曲显示器在内的柔性消费电子产品。在本文中，我们提出了一种使用通用转移方法开发的柔性薄膜 LIB，它能够实现各种不同的柔性 LIB，而不受电极化学的限制。此外，它可以在聚合物衬底上形成高温（HT）退火电极，以实现高性能 LIB。然后，可弯曲 LIB 与柔性发光二极管（LED）集成，形成一个一体化的柔性电子系统。出色的电池性能通过有限元分析（FEA）模拟得到了很好的验证和支持。
