I suppose I should ask first, is this what is done in typical batteries? Do they strip off pretty much every available electron? It would seem not because 1 mole of lithium, weighing roughly 7 grams, would have roughly 19 MJ of potential if all 3 electrons were stripped off it, but only 500 kJ if only the first electron were stripped.

Just looking at a AA battery for example, assuming it puts out say 2 volts... If it has a 2000 mAh capacity, that's 4 Watt-hours of power stored. That only requires something like 0.028 grams of actively used Lithium in the battery (assuming only one electron is stripped), or 0.0007 grams (assuming all 3 electrons are stripped).

I guess I'm asking, is it really theoretically possible to store over 5 kilowatt hours of energy potential in 7 grams of lithium by stripping all 3 electrons?

The next logical step on this question is this: The 29th ionization energy of Copper is 1.1 GJ/mol - The 28th ionization energy is 1 GJ/mol, the 27th is 250 MJ/mol, and so on... Adding up all of those from the 1st through the 29th ionization energy, you've got a CRAPTON of potential energy if you stripped 29 electrons off of 1 Mole of copper. Like, we're talking on the order of Megawatt hours of potential in 63 grams of copper.

Is this theoretically possible? If so, is it "just" an engineering problem that is preventing the development of batteries like this? What all is limiting this development?
