SUMMARY

Batteries are devices that store energy through chemical reactions, distinguishing them from capacitors, which store excess electrons. The limitations of modern batteries are primarily related to their energy density, which is constrained by the physical and chemical properties of the materials used. Current advancements in battery technology are focused on maximizing space and mass efficiency, with ongoing research into new materials and designs. Resources such as Wikipedia and Battery University provide comprehensive information on battery types and their applications.

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?
 
Physics news on Phys.org
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.
