[ theoretically = far out imagination = trolling for funding ]

Bert didn't say anything about lead-acid batteries. He said that a 12V battery is two 6V batteries, whereas automotive lead-acid batteries comprise six 2V cells in series. If he was talking about car batteries, he was wrong. Offhand I don't know of any commercially available six volt primary cells. However, he was right in that every otherwise unused cubic inch of an electric car should be crammed with storage cells of whatever chemistry. > Almost everything in my Prius and electronics is lithium ion, or lithium > whatever, or silver oxide. The HV (main) batteries in the Prius are Ni-MH types. https://en.wikipedia.org/wiki/Toyota_Prius#Batteries Have you considered the carbon footprint of the production of the lanthanum and neodymium in your Prius, and the materials in the other battery types you mention? Lithium in particular is mass-produced by electrolysis of lithium salts. > Gone are the days of lead acid batteries and alkaline batteries. You do know that modern rechargeable alkaline batteries contain no mercury or cadmium, and are fairly common, don't you? https://en.wikipedia.org/wiki/Rechargeable_alkaline_battery > I'm looking forward to the contributions of graphene to capacitors and > battery technology. Keep looking, because there are severe technological barriers to its adaptation to mass manufacturing. Mark L. Fergerson
