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.
I. In voltaic cells the flow of electrons is spontaneous. II. In electrolytic cells electrons flow in the external circuit (through the wire) from the anode to the cathode. III.
