washer click to hear : washer

Disk that compresses the depolarizing mix.

sealing plug click to hear : sealing plug

Material that seals the battery.

positive terminal click to hear : positive terminal

Polarity element of the battery from which the current flows.

top cap click to hear : top cap

Upper metal cover; the positive terminal is located at its center.

Porous paper combined with a chemical paste (ammonium chloride) that separates the two electrodes; this allows electrons to pass, thus conducting electricity.

jacket click to hear : jacket

Battery’s protective plastic casing.

carbon rod (cathode) click to hear : 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.

depolarizing mix click to hear : depolarizing mix

Mixture of carbon and manganese dioxide that augments conductivity by acting as a barrier to polarization.

zinc can (anode) click to hear : zinc can (anode)

Zinc receptacle that constitutes the battery’s positive electrode (anode).

bottom cap click to hear : bottom cap

Lower metal cover; the negative terminal is located at its center.

negative terminal click to hear : negative terminal
