Abstract:
An electrode for a battery includes an iron-containing substrate and a cobalt ferrite layer disposed over the iron-containing substrate. Advantageously, the cobalt ferrite layer inhibits corrosion of the iron-containing substrate. A nickel hydroxide layer is disposed over the cobalt ferrite layer. A battery incorporating the electrode is also provided.
