The first evidence of batteries comes from archaelogical digs in Baghdad, Iraq. This first "battery" was dated to around 250 B.C. and was used in simple operations to electroplate objects with a thin layer of metal, much like the process used now to plate inexpensive gold and silver jewlery. One of the first uses for batteries. Batteries were re-discovered much later by a man named Alessandro Volta after which the unit of electical potential was named, the volt. Alessandro Volta was born in 1745 and died in 1827, but not before developing what would come to be the most important part of life as we know it. He developed a device made of alternated pieces of electrolyte (sodium chloride, a.k.a. table salt) soaked discs, zinc and copper discs stacked in a column with a wire connected to a copper plate on the top and a wire connected to a zinc plate on the bottom, left. Volta demonstrated his new re-discovery, the Voltaic Cell to Napoleon Bonaparte in 1801, right. (Volta is standing in the centre of the picture, Napoleon is sitting to the picture's left.) Since 1801 many aspects of batteries have changed. Their shapes have gone through a few changes, there are now many different types of materials used to construct batteries, all resulting in differently performing batteries for many different applications. As you, the reader, delve through my project, I will attempt to display and explain some of the more popular and effective technologies developed over the last 20 years with Nickel-based cells, Lithium-based cells, along with a few less known fast-developing battery technologies. Enjoy!
