the battery and capacitor combination for power backup, Electrical Engineering

Why do wenot see the battery and capacitor combination for power backup?

Ans) There are "super capacitors" that are used for power backup - they are well-organized for short-term power take-over, but they are leaky and are not good for long term. Batteries tend to expire slowly, more slowly than the leakage on a power backup capacitor, so the capacitor does not do any good.
