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 are pushed into a chamber, and waste zinc oxide is pumped into a waste tank or bladder inside the fuel tank. Fresh zinc paste or pellets are taken from the fuel tank. The zinc oxide waste is pumped out at a refueling station for recycling. Alternatively, this term may refer to an electrochemical system in which zinc is a co-reactant assisting the reformation of hydrocarbons at the anode of a fuel cell. Cobalt oxide/carbon nanotube hybrid oxygen reduction catalyst and Nickel-iron layered double hydroxide oxygen evolution cathode catalysts exhibited higher catalytic activity and durability in concentrated alkaline electrolytes than precious
