Super iron battery

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)), this is, potassium ferrate (K₂FeO₄) or barium ferrate (BaFeO4), used in this new class of batteries.^[1]

As of 2004 chemist Stuart Licht of the University of Massachusetts in Boston was leading research into a Super-iron battery.

"…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^[2]

It uses the same zinc anode and electrolyte as an alkaline battery, but its capacity is around 50% higher.^[3]
