Only your device can change its energy needs, not the storage device.
Capacitors are nice because they can be charged quickly and have much longer life than a battery. They also have much less internal resistance, thus they can discharge faster.( higher power due to energy over time release). Less internal resistance also means less wasted energy since power equals current squared times resistance.
