Capacitors store energy like static electricity. Imagine two metal plates one positively charged and one negatively charged, really close together but not touching. Until something does connect them and a surge of electrons move to cancel out the charge.
Same kind of potential energy you have built up whenever you touch a metal door knob and it shocks you. Lightning is also a form of static electricity discharge.

Batteries how ever work chemically. They exploit a type of chemical reaction often called a redox reaction, in which, two dissimilar materials (like lead and lead oxide in a car battery) give or take electrons from one another.
This same kind of chemical reaction is also how your body produces electricity to live. There are lots of details removed, but the both reactions are redox reactions.
