  2. Nickel–iron battery - Wikipedia

    en.wikipedia.org/wiki/Nickeliron_battery

    Thomas Edison in 1910 with a nickel-iron cell from his own production line. The nickel–iron battery (NiFe battery) is a rechargeable battery having nickel(III) oxide-hydroxide positive plates and iron negative plates, with an electrolyte of potassium hydroxide. The active materials are held in nickel-plated steel tubes or perforated pockets.

    en.wikipedia.org/wiki/History_of_the_battery

    Nickel-iron batteries manufactured between 1972 and 1975 under the "Exide" brand, originally developed in 1901 by Thomas Edison. A set of modern batteries Waldemar Jungner patented a nickel–iron battery in 1899, the same year as his Ni-Cad battery patent, but found it to be inferior to its cadmium counterpart and, as a consequence, never ...

  5. 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 ...

    It can be assembled in the discharged state, using NaCl, Al, nickel and iron powder. The positive electrode is composed mostly of materials in the solid state, which reduces the likelihood of corrosion, improving safety. [16] Its specific energy is 100 Wh/kg; specific power is 150 W/kg. The β-alumina solid ceramic is unreactive to sodium metal ...

  7. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    Thomas Edison's nickel–iron batteries manufactured under the "Exide" brand, originally developed in 1901 by Thomas Edison, use a potassium hydroxide electrolyte. Batteries with alkaline (rather than acid) electrolyte were first developed by Waldemar Jungner in 1899, and, working independently, Thomas Edison in 1901.

    Nickel battery may refer to: . Nickel–cadmium battery, a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes; Nickel–iron battery, a type of rechargeable battery using nickel(III) oxide-hydroxide positive plates and iron negative plates, with an electrolyte of potassium hydroxide

  9. Nickel–hydrogen battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–hydrogen_battery

    A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]
