The recent boom in flexible and wearable electronic devices has increased the demand for flexible energy storage devices. The flexible lithium-sulfur (Li-S) battery is considered to be a promising candidate due to its high energy density and low cost. Herein, a flexible Li-S battery was fabricated based on an all-in-one integrated configuration, where a multiwalled carbon nanotubes/sulfur (MWCNTs/S) cathode, MWCNTs/manganese dioxide (MnO₂) interlayer, polypropylene (PP) separator, and Li anode were integrated together by combining blade coating with vacuum evaporation methods. Each component of the all-in-one structure can be seamlessly connected with the neighboring layers. Such an optimal interfacial connection can effectively enhance electron- and/or load-transfer capacity by avoiding the relative displacement or detachment between two neighboring components at bending strain. Therefore, the flexible all-in-one Li-S batteries display fast electrochemical kinetics and have stable electrochemical performance under different bending states.

灵活的多合一锂硫电池

柔性和可穿戴电子设备的近来热潮增加了对柔性能量存储设备的需求。柔性锂硫（Li-S）电池由于其高能量密度和低成本而被认为是有前途的候选者。本文中，基于多合一集成构造制造了柔性Li-S电池，其中多壁碳纳米管/硫（MWCNTs / S）阴极，MWCNT /二氧化锰（MnO ₂）中间层，聚丙烯（PP）隔膜和锂阳极通过将叶片涂层与真空蒸发方法结合在一起而集成在一起。多合一结构的每个组件都可以与相邻层无缝连接。通过避免在弯曲应变下两个相邻组件之间的相对位移或分离，这种最佳的界面连接可以有效地增强电子和/或负载传递能力。因此，柔性多合一锂电池具有快速的电化学动力学性能，并且在不同的弯曲状态下具有稳定的电化学性能。
