Scientists in Hong Kong have designed a redox flow battery with electrolytes made of zinc and cerium. They claim to have solved the incompatibility issue posed by these two elements. The device achieved a record average Coulombic efficiency of 94% during cycling. October 7, 2022 Emiliano BelliniResearchers from the City University of Hong Kong have developed a redox flow battery (RFB) based on electrolytes made of zinc (Zn) and cerium (Ce) that they claim may be an ideal solution for renewable energy storage, due to its design flexibility.“The Zn-Ce flow battery has the advantages of moderate cost and high energy density, but suffers from low efficiency,” researcher Walid Daoud told pv magazine, noting that the devices usually have a lifespan of just a few cycles. “Thus, we proposed a new cell design to improve its efficiency and stability.”The battery features two membranes…
