Super iron battery

In 1999, researchers in Israel reported a new type of alkaline battery, called a "super-iron" battery. This battery uses the same anode reaction as an ordinary alkaline battery but involves the reduction of Fe042- ion (from K2Fe04) to solid Fe(OH)3 at the cathode. 

A promising new battery now under development employs unusual iron(VI) compounds at the anode. Because iron(VI) is such a strong oxidizing agent, its compounds are normally very unstable, but these problems seem to have been solved by removing contaminants such as cobalt and nickel. These so-called super-iron batteries reportedly can furnish 50% more energy than conventional dry cell batteries.
