柔性锂离子电池（LIB）可以无缝集成到柔性显示器、可穿戴设备和智能卡等柔性设备中，为机械变形下的稳定运行提供动力。理想的柔性电池应该同时具有高柔性、高能量密度和高功率密度，这三者往往是相互冲突的。在这个角度，我们分析了基于结构设计的柔性电池从组件级和设备级。本文综述了柔性锂离子电池的最新进展，包括电池组件的多孔结构、超薄设计、拓扑结构和具有解耦概念的电池结构。最后，对柔性电池的未来进行了展望和讨论。
Flexible lithium-ion batteries (LIBs) can be seamlessly integrated into flexible devices, such as flexible displays, wearable devices, and smart cards, to provide power for steady operation under mechanical deformation. An ideal flexible battery should have high flexibility, high energy density, and high power density simultaneously, which are often in conflict with each other. In this Perspective, we analyze the flexible batteries based on structural designs from both the component level and device level. Recent progress in flexible LIBs, including advances in porous structures for battery components, superslim designs, topological architectures, and battery structures with decoupling concepts, is reviewed. In the end, perspectives on the future of flexible batteries are presented and discussed.
