Web12. feb 2024 · A type of chemical reaction in which oxidation and reduction occurs is called a redox reaction, which stands for reduction-oxidation. The oxidation of a metal by oxygen gas could then be explained as the metal atom losing electrons to form the cation (being oxidized) with the oxygen molecule gaining electrons to form oxygen anions. Web2. feb 2024 · The iron-chromium redox flow battery contained no corrosive elements and was designed to be easily scalable, so it could store huge amounts of solar energy indefinitely. A 200-watt demonstration unit of the flow battery NASA built in the 1970s. (Supplied: NASA)
