In a zinc–manganese dioxide AA battery, the zinc can is the negative terminal through which the electric current flows into the device. The zinc is oxidised according to the followinghalf-equation.
Zn(s) → Zn2+(aq) + 2 e− [E° = -0.7626 volts]
The positive terminal is a mixture of chemicals – usually a mixture of manganese dioxide powder, carbon and an electrolyte to increase theelectrical conductivity. A carbon electrode rod also is placed inside the middle of the battery, connecting the two metal-capped ends of opposite charge and serving as the positive terminal.The reaction is as follows:
