Safe rechargeable batteries of improved energy density and high power performance are urgently needed for the development of large electric devices. Herein, an Li‐based organic liquid anode is proposed, and an organic oxygen battery with a metal organic framework membrane separator is realized, which is able to conduct Li ions and separate other large species in the system. Equipped with the dual redox mediator strategy, the organic oxygen battery exhibits superior rate performance with long cycling life and low overpotential. A “solid electrolyte interface”‐like layer is observed between the organic liquid anode and the ion conducting separator. This work not only introduces a new type of anode for Li‐based batteries, but also provides fundamental insights for the better application of biphenyl‐based liquid anodes.

装有基于锂的液体阳极和MOF隔板的安全有机氧电池

大型电气设备的开发迫切需要提高能量密度和高功率性能的安全可充电电池。本文提出了一种基于锂的有机液体阳极，并实现了带有金属有机骨架膜隔板的有机氧电池，该隔板能够传导锂离子并分离系统中的其他大分子。配备双重氧化还原介体策略，有机氧气电池具有出色的倍率性能，长循环寿命和低过电位。在有机液体阳极和离子导电隔板之间观察到类似“固体电解质界面”的层。这项工作不仅为锂基电池引入了一种新型的阳极，而且为联苯基液态阳极的更好应用提供了基础见解。
