Super-iron battery
From Wikipedia, the free encyclopedia
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]
