A low-cost and efficient high-temperature oxygen evolution reaction electrode is a big challenge. Here, the authors report an iron-base electrode with an in situ formed lithium ferrite for enhanced stability and catalytic activity in molten carbonate and chloride salts and achieve kiloampere-scale electrolysis.
