Main Question or Discussion Point

I would like to know what batteries are, are they just any physical thing that can have and hold electrons more to one side than the other? What are the limitations to how much charge can be held in a certain amount of space, or in a certain amount of mass? How close are we to that limitation with say our most space or mass efficient batteries?

Wow, very broad questions. In general, batteries store energy in terms of chemical reactions. A device which stores an excess of electrons (charge) is called a capacitor, not a battery.

As for your other questions, there are many kinds of batteries. I suggest Wikipedia as good place to study them.
