Organic molecules are promising active materials for nonaqueous redox-flow batteries (RFBs), but suffer from poor cycling stability. Here, the authors introduce azobenzene-based molecules as new type of highly soluble and stable active materials to realize high-capacity and long-life nonaqueous RFBs.
Hence, there is an urgent need to develop membrane-free batteries that use flowable nonaqueous electrolytes with high voltage and energy density. In this work, we report an all-nonaqueous biphasic membrane-free battery that shows high voltage and energy density under both static and flow conditions.
With the reversible redox activity of azo group in π-conjugated structures, azobenzene-based molecules represent a class of promising redox-active organics for potential grid-scale energy storage systems. Developing efficient energy storage technologies is essential to effectively alleviate the growing energy crisis and environmental issues 1.

The NARFB exhibits EE of 63.5% at an ultra-high current density of 100 mA cm −2. The battery delivers a peak power density of 336 mW cm −2. Azobenzene (azoB) is a promising anode active material for nonaqueous redox flow battery (NARFB), but the battery performance assembled with azoB is rather poor.
With the merits of high energy density, cost effectiveness, high safety, and simple manufacturing, anode-free batteries (AFBs) are emerging as promising alternatives for next-generation energy storage devices.
