Zinc–carbon battery
Videos
A zinc–carbon battery is the generic “heavy duty” disposable battery. They were some of the earliest batteries made for consumer devices and while they have been overtaken in recent times by the longe
Old 3 V zinc–carbon battery (around 1960), with cardboard casing housing two cells in series.
Progressive corrosion of zinc–carbon batteries
Disassembled zinc chloride cell (similar to zinc carbon cell). 1: entire cell, 2: steel casing, 3: zinc negative electrode, 4: carbon rod, 5: positive electrode (manganese dioxide mixed with carbon powder and electrolyte), 6: paper separator, 7: polyethylene leak proof isolation, 8: sealing rings, 9: negative terminal, 10: positive terminal (originally connected to carbon rod).
Ammonium chloride

Ammonium chloride is an inorganic chemical compound with the chemical formula NH4Cl, also written as Cl. It is an ammonium salt of chloride. It consists of ammonium cations + and chloride anions Cl−.
Zinc–carbon battery
…dry cell that provides direct electric current from the electrochemical reaction between zinc (Zn) and manganese dioxide (MnO2) in the presence of an ammonium chloride (NH4Cl) electrolyte. It produces a voltage of about 1.5 volts between the zinc anode, which is typically constructed as a cylindrical container for the…
Crystalline ammonium chloride
Ammonium chloride pyrolyses and reforms into ammonium-chloride smoke after cooling.
