2. Nickel–cadmium battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–cadmium_battery

   The capacity of a Ni–Cd battery is not significantly affected by very high discharge currents. Even with discharge rates as high as 50C, a Ni–Cd battery will provide very nearly its rated capacity. By contrast, a lead acid battery will only provide approximately half its rated capacity when discharged at a relatively modest 1.5C.

3. 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] The nickel–hydrogen battery was patented in the ...

4. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   Nominal cell voltage. 1.2 V. A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel-cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.

5. Nickel–zinc battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–zinc_battery

   Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power. [6]

7. Waldemar Jungner - Wikipedia

   en.wikipedia.org/wiki/Waldemar_Jungner

   Ernst Waldemar Jungner (19 June 1869 – 30 August 1924) was a Swedish inventor and engineer. In 1898 he invented the nickel-iron electric storage battery (NiFe), the nickel-cadmium battery (NiCd), and the rechargeable alkaline silver-cadmium battery (AgCd). As an inventor, he also fabricated a fire alarm based on different dilutions of metals.
