Electrochemical Studies of Uranium (IV) in an Ionic Liquid–DMF Mixture to Build a Redox Flow Battery Using Uranium as an Electrode Active Material

The electrochemical behavior of uranium (IV) tetrachloride in ionic liquid–DMF mixture was studied for the first time in order to build a redox flow battery (RFB) using U as an electrode active material. A quasi-reversible UIII/UIV couple was observed in an [EtMeIm][Tf2N]–DMF mixture (1:1 v/v) at 29...

description The electrochemical behavior of uranium (IV) tetrachloride in ionic liquid–DMF mixture was studied for the first time in order to build a redox flow battery (RFB) using U as an electrode active material. A quasi-reversible UIII/UIV couple was observed in an [EtMeIm][Tf2N]–DMF mixture (1:1 v/v) at 298 K and the reversibility improved by the addition of Cl−. The repeatability of UIII/UIV couple was high. These results indicated that the UIII/UIV couple is suitable for the anode reaction of the RFB.
