The Leclanché Cell
The first cell developed by Georges Leclanché in France was a wet cell having its electrodes immersed in a liquid. Nevertheless, it was rugged and easy to manufacture and had a good shelf life. He later improved the cell by substituting a moist ammonium chloride paste for the liquid electrolyte and sealing the cell. The resulting cell was referred to as a dry cell. It could be used in various positions and moved about without spilling. Carbon-zinc dry cells are sold to this day in blister packages labeled "heavy duty" and "transistor power". The anode of the cell was zinc, which was made into a cup or can which contained the other parts of the battery. The cathode was a mixture of 8 parts manganese dioxide with one part of carbon black, connected to the positive post or button at the top of the battery by a carbon collector rod. The electrolyte paste may also contain some zinc chloride. Around 1960 sales of Leclanché cells were surpassed by the newer alkaline-manganese cell.
