something about the battery and the capacitor is the same and I am at

differences better.

The student has an excellent point.

For almost all practical purposes, a battery can be
thought of as a capacitor with a huuuuge capacitance
and crummy high-frequency performance.

Relatedly, How do the "super capacitors" work which have a capacitance on
the order of farads in a small package? Is it more a battery technology
than capacitor technology?
