When weighing options for energy storage, different factors can be important, such as energy density or power density, depending on the circumstances. Generally batteries -- which store energy by separating chemicals -- are better for delivering lots of energy, while capacitors -- which store energy by separating electrical charges -- are better for delivering lots of power (energy per time). It would be nice, of course, to have both.
