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
Photoflash battery of a zinc-carbon cell is generally made of powdered carbon black (or acetylene black), manganese dioxide and electrolyte. The MnO to carbon ratios vary between 10:1 and 3:1 for general purpose cells. A 1:1 mixture is used for photoflash batteries. This allows a high current output with intermittent use, perfect for photoflash use.These cells have reduced capacity compared to those with a higher content of MnO. Another common type of photoflash battery was a higher-voltage series assembly of cells, often totalling 22.5 volts, used in battery–capacitor flash units. The battery slowly charged a capacitor, which then was discharged through a
