The Coke Oven Battery. A Coke Oven Battery consisted of a great many ovens, sometimes hundreds of ovens, in a row. Some mines also employed parallel batteries as in the illustration. Salem Mine No.1 Coke Works, Salemville, PA, used three banks of single ovens, containing 280 bee-hive coke ovens.
Differences Between Voltaic and Electrolytic Cells. -Voltaic cells use spontaneous reactions to produce energy-Electrolytic cells use non-spontaneous reactions that requires energy-Voltaic cells have a negative anode and a positive cathode-Electrolytic cells have a positive anode and a negative cathode.
A galvanic cell is also called a voltaic cell. The spontaneous reactions in it provide the electric energy or current. Two half cells can be put together to form an electrolytic cell, which is used for electrolysis. In this case, electric energy is used to force nonsponaneous chemical reactions.
