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 are designed by the manufacturer to be rechargeable. Rechargeable alkaline cells are constructed very similarly to disposable alkaline cells. A cathode paste is pressed into a steel can that forms the positive terminal of the battery. The negative electrode consists of zinc powder suspended in a gel, with a steel nail contact that runs to the base of the cell to form the negative terminal. Features of the rechargeable alkaline that differ from a disposable alkaline cell include the presence of barium sulfate or other additives in the cathode mix, which improve cycling and increase capacity by preventing the formation
