Method for increasing electrolytic efficiency of a fusion electrolysis with anodic oxygen generation

摘要

A method for increasing the current yield or electrolytic efficiency of a fusion electrolysis, especially water electrolysis, with which an anodic oxygen separation occurs. Lithium ions are added to the fusion electrolyte. Such lithium ions may be added by adding lithium as hydroxide or fluoride, sulfate or carbonate. The lithium addition amounts to at least 15 Mol % of the melt. Electrolyte is formed by a lithium hydroxide containing alkali hydroxide melt.
