Batteries don't actually store energy, the space between the electrodes is filled with an electrolyte an iconic liquid that conducts electricity.

It’s actually an ion-charged electrolyte paste, but the answer is spot on.

You have to be a bit careful with the "storing" bit. If you charge an accumulator (like a car battery) you are certainly placing energy inside it, hence the term "Potential Difference" when referring to voltages generated by a battery. That "Potential" is Potential Energy.
