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
Nickel–zinc battery provided for, and excess hydrogen will eventually vent, adversely affecting battery cycle life. A typical charger for NiZn batteries specifically does not trickle charge after the battery is fully charged, but shuts off. Electrolyte: KOH Overall reaction: Zn + 2 NiO(OH) + H2O ↔ ZnO + 2 Ni(OH)2 Parasitic reaction: Zn + 2 H2O → Zn(OH)2 + H2 Nickel–zinc battery A nickel–zinc battery, abbreviated NiZn, is a type of rechargeable battery similar to NiMH batteries, but with a higher voltage of 1.6 V. Larger nickel–zinc battery systems have been known for over 100 years. Since 2000, development of a stabilized
