Electrochemical behaviour of iron oxide electrodes in alkali solutions

Abstract

The need for understanding the electrochemical behaviour of iron oxide in iron electrodes arises mainly due to development of iron electrodes for alkaline batteries. The charge and discharge behaviours of pressed and sintered iron oxide electrodes in electrolytic iron powder were studied by triangular potential sweep voltammetry, chronopotentiometry open circuit potential decay and recovery transient techniques. The role of oxide in the iron electrode for the nickel-iron cell is discussed.
