WebSep 18, 2024 · O-EDS mapping does not show a significant oxygen level in the cycled negative electrode in cell Fe2, which indicates that oxidation should be excluded as the main cause of cell failure. For Fe3 to Fe5, the negative electrodes are severely oxidized, whereas no obvious pulverization is observed. WebIn effect, the electron has been transferred from the iron to the oxygen. This combined redox reaction is possible if there is a surplus of Fe+2 and oxygen simultaneously. The iron serves as the reducing agent, and is itself oxidized. The oxygen serves as the oxidizing agent and is itself reduced.
