Bill A.—
There is some info on usenet. If you are serious about studying up on the matter, start by searching Google Groups for "sci.chem.electrochem Frequently Asked Questions" but—fair warning—you won't get 6-word answers to your questions.
You may want to also search “sci.chem.electrochem.battery”… {Caution—If the term ‘usenet’ has no meaning, you may be entering intense [and vast!] territory. It’s far older than the WWWeb stuff.} Good luck.
