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
Zinc–air battery Approximately 35% of the world's supply, or 1.8 gigatons of zinc reserves are in the United States, whereas the U.S. holds only 0.38% of known lithium reserves. Initial rechargeable zinc air batteries, developed for use in vehicles, were used for buses in Singapore. Their developer, Miro Zorič, chose zinc air chemistry specifically due to zinc air battery production requiring only abundant raw materials without requiring rare earth materials. When used to power vehicular AC (induction) drive trains, this would allow global road transport electrification, without destabilizing global supply chains or cause adverse raw material bottlenecks.
