Electrode reaction cannot be reversed, and the identities of the anode and cathode are therefore fixed. The anode is always the negative electrode. The cell can be discharged but not recharged. A secondary cell, for example a rechargeable battery, is a cell in which the chemical reactions are reversible. When the cell is being charged, the anode becomes the positive (+) and the cathode the negative (−) electrode. This is also the case in an electrolytic cell. When the cell is being discharged, it behaves like a primary cell, with the anode as the negative and the cathode as the positive
Electrolytic Zinc Electrolytic Zinc Electrolytic Zinc or the Electrolyic Zinc Company of Australasia (frequently abbreviated to "EZ" ) was the company that operated a Zinc refinery on the banks of the Derwent River in Risdon in Hobart in Tasmania between 1916 and 1984. The refinery was often given names such as the "Risdon works", the "Zinc works","reduction works" The current usage and place name located at the Risdon works is identified as Lutana. The operations of the Risdon works were tied in with the mining of zinc in Rosebery on the West Coast of Tasmania. The company started operation in 1916 at
