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.
The cell with the larger voltage is discharged, making it a galvanic cell, so P is the cathode and N is the anode as described above. But, the cell with the smaller voltage charges, making it an electrolytic cell. In the electrolytic cell, negative ions are driven towards P and positive ions towards N.
