A new-type redox battery has been developed. Some ruthenium complexes in organic electrolyte solution were utilized as the electrode active materials. A single cell consisting of [Ru(bpy)3]2+ complex in acetonitrile solution had an open circuit voltage of 2.6 V and a discharge current of 5 mA cm−2 (at a smooth carbon electrode). The characteristics of this type of cell were much influenced by such factors as the diaphragm material and the concentration of the complex. A cell with flowing electrolyte was also constructed and its charge-discharge performance was examined.
