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–carbon battery internal resistance, while more manganese dioxide improves storage capacity. Flat cells are made for assembly into batteries with higher voltages, up to about 450 volts. Flat cells are stacked and the whole assembly is coated in wax to prevent electrolyte evaporation. In a zinc–carbon dry cell, the outer zinc container is the negatively charged terminal. The zinc is oxidised according to the following half reactions: Anode (oxidation reaction, marked -) Cathode (reduction reaction, marked +) Other side-reactions are possible, but the overall reaction in a zinc–carbon cell can be represented as: If zinc chloride is substituted for ammonium chloride (i.e.
