A primary cell is any kind of electrolytic cell in which the electrochemicalreaction of interest is not reversible. The most common primary cells today are found in alkaline batteries; earlier carbon-zinc cells, with a carbon post as cathode and a zinc shell as anode were prevalent. Unlike a secondary cell, attempting to reverse the reaction in a primary cell via recharging is dangerous and can lead to a battery explosion. A related difference is that primary batteries use up the materials in one or both of their electrodes, while, ideally, the reversibility of the reactions in a secondary cell allows them to be restored to almost the same fully charged condition on each recharging. Electrolytic cells are composed of an electrolyte (usually water or another solvent capable of dissolving various ions of interest), a cathode and an anode. ...
