Super-iron battery

The Super-iron battery is a moniker for a proposed class of rechargeable electric battery. Such batteries feature cathodes composed of ferrate salts, commonly potassium ferrate (K
₂FeO
₄) or barium ferrate (BaFeO
₄).^[1][2][3] 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 toxic cadmium, manganese and nickel.^[1][2][3] Another attraction is potentially higher energy capacity.^[1]
