A dry cell uses a paste electrolyte, with only enough moisture to allow current to flow. Unlike a wet cell, a dry cell can operate in any orientation without spilling, as it contains no free liquid, making it suitable for portable equipment.
A common dry cell is a zinc-carbon battery, sometimes called the dry Leclanché cell, with a nominal voltage of 1.5 volts, same as the alkaline battery (since both use the same zinc–manganese dioxide combination).
A standard dry cell comprises a zinc anode, usually in the form of a cylindrical pot, with a carbon cathode in the form of a central rod.
The electrolyte is ammonium chloride in the form of a paste next to the zinc anode.
The remaining space between the electrolyte and carbon cathode is taken up by a second paste consisting of ammonium chloride and manganese dioxide, the latter acting as a depolariser.
In some designs, the ammonium chloride is replaced by zinc chloride.
