Renewable energy-related technologies have become more important due to the increasing energy consumption. Herein, we put forward a novel organic flow desalination battery (ORFDB) using redox-active organic molecule electrolyte materials dissolved in the aqueous sodium chloride feed. Riboflavin-5'-phosphate sodium salt dihydrate (FMN-Na) is used as the anolyte, and the catholyte is 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO). Sodium and chloride ions in salt feed were moved respectively to anolyte and catholyte by electrochemical reaction of electrolytes during the charge process, and return to the feed during the discharge process. This ORFDB system possesses the stable stability up to fifty cycles and the excellent rate performance. This ORFDB exhibits the cost-effective renewable energy storage and the possibility of salt removal based on the electrochemistry of organic molecules.
