The Super-iron battery is a moniker for a proposed class of rechargeable electric battery. Such batteries feature cathodes composed of ferrate salts, either potassium ferrate (K
4) or barium ferrate (BaFeO
4). One attraction to the proposed device is that the spent cathode would consist of a rust-like material, which is preferable to batteries based on cadmium, manganese and nickel.
