Dry cell battery - Encyc

A common dry cell battery is the zinc-carbon battery, using a cell sometimes called the dry Leclanché cell, with a nominal voltage of 1.5 volts, the same nominal voltage as the alkaline battery (since both use the same zinc-manganese dioxide combination).Harvesting Chemicals from a Battery | Make:,Note that the battery in this tutorial is a zinc-carbon dry cell. This tutorial does not cover the dismantling of an alkaline-type cell. Alkaline cells are of slightly different internal construction and contain the strong base potassium hydroxide as an electrolyte, which is rather more dangerous to handle than the ammonium chloride/zinc chloride mixtureWhat Is Manganese Used For? | Reference,Manganese(IV) oxide is the black material found in the original type of dry cell battery. In newer alkaline batteries, however, the electrolyte responsible for accepting electrons from the zinc is a different chemical.
