Batteries may have existed 1000 or more year before Volta: see Wikipedia's History of the Battery. If this was the case, it's hard to see why such a useful technology disappeared for so long. Perhaps it was banned by religious forces claiming it was the work of the devil -- or a scientific threat to religion. More likely there was a huge patent dispute which completely halted the Progress of Science and useful Arts :-)
