2. Nickel–iron battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–iron_battery

   A 50 volt nickel–iron battery was the main D.C. power supply in the World War II German V-2 rocket, together with two 16 volt batteries which powered the four gyroscopes (turbine powered generators supplied A.C. for its magnetic amplifier driven servomechanisms). A smaller version was used in the V-1 flying bomb.

   The ZEBRA's liquid electrolyte freezes at 157 °C (315 °F), and the normal operating temperature range is 270–350 °C (520–660 °F). Adding iron to the cell increases its power response. [16] ZEBRA batteries are currently manufactured by FZSoNick [18] and used as a power backup in the telecommunication industries, Oil&Gas and Railways. It ...

6. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   Nickel–cadmium batteries have been almost completely superseded by nickel–metal hydride (NiMH) batteries. The nickel–iron battery (NiFe) was also developed by Waldemar Jungner in 1899; and commercialized by Thomas Edison in 1901 in the United States for electric vehicles and railway signalling. It is composed of only non-toxic elements ...

7. Metal–air electrochemical cell - Wikipedia

   en.wikipedia.org/wiki/Metal–air_electrochemical...

   Most of the batteries currently being developed utilize iron oxide powders to generate and store hydrogen via the Fe/FeO reduction/oxidation (redox) reaction (Fe + H 2 O ⇌ FeO + H 2). [20] In conjunction with a fuel cell, this enables the system to behave as a rechargeable battery, creating H 2 O/H 2 via the production and consumption of ...
