Lithium–oxygen (Li–O2) batteries possess the highest theoretical energy density (3500 Wh kg−1), which makes them attractive candidates for modern electronics and transportation applications. In this work, an inexpensive, flexible, and wearable Li–O2 battery based on the bifunctional redox mediator of InBr3, MoS2 cathode catalyst, and Fomblin-based oxygen permeable membrane that enable long-cycle-life operation of the battery in pure oxygen, dry air, and ambient air is designed, fabricated, and tested. The battery operates in ambient air with an open system air-breathing architecture and exhibits excellent cycling up to 240 at the high current density of 1 A g−1 with a relative humidity of 75%. The electrochemical performance of the battery including deep-discharge capacity, and rate capability remains almost identical after 1000 cycle in a bending fatigue test. This finding opens a new direction for utilizing high performance Li–O2 batteries for applications in the field of flexible and wearable electronics.

高性能透气柔性锂空气电池

锂氧(Li-O 2)电池具有最高的理论能量密度(3500 Wh kg -1),这使其成为现代电子和交通应用的有吸引力的候选者。在这项工作中,基于 InBr 3的双功能氧化还原介质、MoS 2阴极催化剂和基于 Fomblin 的透氧膜,一种廉价、灵活且可穿戴的 Li-O 2电池能够使电池在纯氧、干燥空气和环境空气经过设计、制造和测试。该电池在环境空气中运行,采用开放式系统呼吸架构,并在 1 A g -1的高电流密度下表现出高达 240 次的出色循环相对湿度为 75%。在弯曲疲劳试验中,电池的电化学性能包括深放电容量和倍率性能在 1000 次循环后几乎保持不变。这一发现为将高性能 Li-O 2电池用于柔性和可穿戴电子领域的应用开辟了新方向。
