A dry-cell battery is a device made of one or more electrochemical cells that convert stored chemical energy into electrical energy.
It contains an electrolyte that is contained within a paste or other moist medium.
A standard dry cell battery includes a zinc anode and a carbon cathode within a central rod.
The electricity-generating reduction reaction usually takes place in a paste made up of ammonium chloride and manganese dioxide in an acidic dry cell in a dry cell battery.
