How ancient is the Battery?

Battery University will challenge even the teaching of the Bible with what is believed to be the first ancient battery discovery while constructing a railway in 1936 near Baghdad. This is referred to as Parthian Battery. The object dates back to the Parthian period and is believed to be 2,000 years old. A clay jar of a prehistoric battery holds an iron rod surrounded by a copper cylinder. When filled with vinegar or electrolytic solution, the pot produces 1.1 to 2 volts. Not all scientists believe the Parthian battery was used for electricity. Others believe it was used for electroplating, such as adding gold or other precious metals to surfaces. The modern use of batteries was started by Volta, who discovered in 1800 that certain fluids would generate a continuous flow of electrical power when used as a conductor. This discovery led to the invention of the first voltaic cell, more commonly known as the battery. In 1802, William Cruickshank designed the first electric battery for mass production. The battery of choice in this period was Lithium-ion, named after their active material, written in whole or specified by their chemical symbols. There are six of the most common Li-ion: Lithium Cobalt Oxide (LiCoO2), Lithium Manganese Oxide (LiMn2O4), Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2 or NMC), Lithium Iron Phosphate (LiFePO4), Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2), and Lithium Titanate (Li4Ti5O12). The Battery University has the most information that I have ever seen in one place about batteries.
