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]
Nickel–iron batteries are being investigated for use as combined batteries and electrolysis for hydrogen production for fuel cell cars and storage. Those "battolysers" could be charged and discharged like conventional batteries, and would produce hydrogen when fully charged. [14] [15] [16]

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.

Artificial satellites, such as communication satellites, require battery systems that can withstand thousands of charge and discharge cycles over the satellite's intended life. [2] Schematic of the internal arrangement of nickel-hydrogen rechargeable battery. Primary batteries are used for relatively short-duration tasks.
The EPA began monitoring for hydrogen fluoride, a highly toxic gas produced by lithium-ion battery fires, and for particulate matter, according to the county’s timeline.
A Duracell AA size alkaline cell, one of the many types of battery. This list is a summary of notable electric battery types composed of one or more electrochemical cells. Three lists are provided in the table. The primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry.
