A zinc–carbon battery is a dry cell primary battery that provides direct electric current from the electrochemical reaction between zinc and manganese dioxide (MnO2). It produces a voltage of about 1.5 volts between the zinc anode, which is typically realized as a container for the battery, and a carbon rod of positive polarity, the cathode, that collects the current from the manganese dioxide electrode, giving the cell its name.
General-purpose batteries may use an aqueous paste of ammonium chloride (NH4Cl) as electrolyte, possibly mixed with some zinc chloride solution. Heavy-duty types use a paste primarily composed of zinc chloride (ZnCl2).
Zinc–carbon batteries were the first commercial dry batteries, developed from the technology of the wet Leclanché cell. They made flashlights and other portable devices possible, because the battery functions in any orientation. They are still useful in low-drain or intermittent-use devices such as remote controls, flashlights, clocks or transistor radios. Zinc–carbon dry cells are single-use primary cells. Zinc-carbon batteries today have been mostly replaced by the more efficient and safe alkaline batteries.
