Super iron battery
From Wikipedia, the free encyclopedia
The Super-iron battery is a new class of rechargeable electric battery.
"Super-iron" is a moniker for a special kind of ferrate salt (iron(VI)). Potassium ferrate (K2FeO4) or barium ferrate (BaFeO4), used in this new class of batteries.[1]
As of 2004[update] chemist Stuart Licht[2] of the University of Massachusetts was leading research into a Super-iron battery.
Use of ferrate cathodes was tested and patented by Amendola[3] as well as other patents.
- "...the new cathode employs salts of an unusual ionic form of iron — hexavalent or superoxidized iron—that readily accept three electrons per ion, Licht explains. The more electrons the cathode can accept, the more electricity the battery can supply." —Peter Weiss[4]
It uses the same zinc anode and electrolyte as an alkaline battery, but its capacity is around 50% higher.[5]

[edit] Environment
Iron rust is nontoxic, preferable over mercury, cadmium, manganese and nickel oxides.
