Posted on 30 June, 2023 by benyamin chahkandi

Summary: Typically, negative electrodes in batteries are made of active materials like metals. Rechargeable metal-air batteries with oxygen-reducing positive electrodes have recently used redox-active organic compounds, such as quinone- and amine-based molecules, as negative electrodes. Here, the redox reactions involve protons and hydroxide ions. These batteries operate well and are almost at their theoretical maximum capacity. Furthermore, using redox-active organic molecules in...
