Zn and the Art of Battery Development: A zinc/polyhalide redox flow battery employs Br − /ClBr 2− and Zn/Zn 2+ redox couples in its positive and negative half‐cells, respectively. The performance of the battery is evaluated by charge–discharge cycling tests and reveals a high energy efficiency of 81%, based on a Coulombic efficiency of 96% and voltage efficiency of 84%. The new battery technology can provide high performance and energy density at an acceptable cost.
