Porous paper combined with a chemical paste (ammonium chloride) that separates the two electrodes; this allows electrons to pass, thus conducting electricity.
Battery’s protective plastic casing.
carbon rod (cathode)
Carbon rod set in the depolarizing mix; it constitutes the battery’s negative electrode (cathode) collecting the electrons returning from the circuit.
Mixture of carbon and manganese dioxide that augments conductivity by acting as a barrier to polarization.
zinc can (anode)
