AbstractWe report a Vanadium-MH rechargeable semi-flow battery with an experimental OCV of 1.93 V and operating voltage of 1.70 V, very high values among rechargeable flow batteries with aqueous electrolytes. This hybrid battery consists of a graphite felt positive electrode operating in a mixed solution of 0.128 mol dm−3 VOSO4 and 2 mol dm−3 H2SO4, and a metal hydride negative electrode in 2 mol dm−3 KOH aqueous solution. The two electrolytes of different pH are separated by a bipolar membrane. The system demonstrated good reversibility and high efficiencies in coulomb (95%), energy (84%), and voltage (88%).
