We can already store electrons in a container, we call that a capacitor. You separate 2 conductive plates with a dielectric and then connect the plates to a voltage source to deposit electrons on one side and remove electrons from the other (creating a difference in electric potential). You can then disconnect the voltage source and you will have electrons in a bottle. When you connect those plates to another circuit, they will discharge. The more surface area you have, the more electrons you can store. Electrolytic capacitors tightly roll the conductors into a spiral for space efficiency.
This cannot be used to gain any more energy than you used to put them all in there.
