Alkaline cells

The most common general-purpose, longer-life cell is the alkaline version
of the dry cell. Outwardly it is much the same in appearance as a standard
dry cell and it also produces a potential difference of 1.5 volts. However,
its construction makes it a better deliverer of electricity than the
standard (acid) dry cell.

The alkaline cell represented below has a powdered zinc anode and a 7 M
KOH(aq) electrolyte in the centre surrounded by manganese dioxide and a
carbon cathode, all in a steel can.
