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 :-)

Alessandro Volta's battery was called the "Voltaic Pile" -- it was constructed of alternating discs of zinc and copper with pieces of cardboard soaked in brine between the metals.

I just read that Benjamin Franklin first coined the term "battery" in 1748 to describe an array of charged glass plates.

Yes, I did plan on listing the per-cell voltages. Thank you for reminding me.

Voltages?

Hi Ivan and welcome

It would be nice if your list had the base voltage of each type, eg 2V for Lead-Acid, 1.2 for NiCd, etc.   Since that has some impact on the choice of a battery, maybe you'll cover that later, though??

Hi Ivan -- I'm guessing that you've ruled Atomic batteries out as a power source for my robot -- I'm very much looking forward to reading your future columns on this topic
