Nickel oxyhydroxide battery

[citation needed] 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 battery in the manufacturing process and in chemical composition.

The chemical difference is the addition of nickel oxyhydroxide to the manganese dioxide and graphite for the cathode.

The cells sustain a higher average voltage during discharge compared to alkaline batteries.

[1] Finer grained graphite in the cathode and a vacuum pouring process that inserts a higher quantity of electrolyte in the cell are used during the manufacturing of the nickel oxyhydroxide cells.
