Technology Description:

The University of Tennessee (UT) will develop a reversible Oxygen Reduction Reaction (ORR) catalyst that can be used both as a peroxide-producing electrolyzer and in reversible air batteries. The ORR catalyst development seeks to significantly improve peroxide electrolysis efficiency and achieve high charge and discharge rates in air-breathing batteries. In conjunction with the new catalyst, an anion exchange membrane (AEM) will be used to further increase the electrolyzer efficiency and reduce peroxide production costs. In the reversible air battery, the AEM increases battery power performance. Finally, a two-phase flow field design will increase both the current density and current efficiency for peroxide production and can also be used in the reversible air battery to build up a high concentration of hydrogen peroxide for energy storage. This technology could also enable onsite hydrogen peroxide production at small scale.
