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
Alkaline battery of energy densities (> 250Wh/L) comparable to lithium-ion if zinc utilization in the batteries is improved. Alkaline batteries are prone to leaking potassium hydroxide, a caustic agent that can cause respiratory, eye and skin irritation. Risk of this can be reduced by not attempting to recharge disposable alkaline cells, not mixing different battery types in the same device, replacing all of the batteries at the same time, storing in a dry place and at room temperature, and removing batteries for storage of devices. All batteries gradually self-discharge (whether installed in a device or not) and dead batteries will eventually leak.
