“…The total process is milder compared with the reaction between Li metal and H 2 O (Figure S2, Supporting Information). Moreover, no bubbles are present within the reaction, indicating that the generation of H 2 is avoided 21. These results make the Bp‐Li anode a safe candidate for the Li‐based battery anode.…”

“…Alkali metals can react with some aromatic hydrocarbons in ether solution, which are commonly used as strong reducing agents and recently investigated as a liquid anode for batteries 19. A biphenyl‐Na liquid anode was firstly studied with a sulfur cathode by Yu et al, and is extended into an oxygen battery by Liang et al20,21 Very recently, Cong et al reported a high rate and long life organic oxygen battery based on a biphenyl‐K liquid anode 22. All these impressive results show the potential of the alkali‐based organic solution as a promising anode for energy storage systems, while the report of its application in the Li‐based battery is still lacking 23.…”

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.

DedicatedtoProfessor Reshef Tenne on the occasion of his 75th birthdayRechargeable seawater batteries have gained recognition as key sustainable electrochemical systems by employing the near-infinite and eco-friendly catholyte seawater.H owever, their practical applications have been limited owing to the low chemicala nd electrochemical stabilityo ft he anode component. Herein, as tability-secured approach was developed by using sodium-biphenyl-dimethoxyethane solution as ar edoxactive functional anolytef or high-performances eawater batteries. This anolyte system shows high electrochemical stability, superior cycle performance, and cost-effectiveness over conventional electrolyte systems. Figure 2.
