Nickel oxyhydroxide battery cells. Nickel oxyhydroxide battery Nickel oxyhydroxide battery (abbr. NiOx, IEC code: Z) is a type of primary cell. It is not rechargeable and must be disposed after a single use. NiOx batteries can be used in high-drain applications such as digital cameras. NiOx batteries used in low-drain applications, have a lifespan similar to an alkaline battery. NiOx batteries produce a higher voltage (1.7V) than alkaline batteries (1.5V) which can cause problems in certain products, such as equipment with incandescent light bulbs (such as flashlights/torches), or devices without a voltage regulator. The nickel oxyhydroxide cell is different from a standard alkaline
Rechargeable alkaline battery different chemical reactions. Some reactions are readily reversible, some are not. The reactions used in most alkaline batteries fall into the latter category. In particular, the metallic zinc generated by driving a reverse current through the cell will generally not return to its original location in the cell, and may form crystals that damage the separator layer between battery anode and electrolyte. The rechargeable alkaline battery was, at one time, cheaper than other rechargeable types. Cells can be manufactured in the fully charged state and retain capacity well. Their capacity is about 2/3 that of primary cells. They are of
