Batteries are one of most cost-effective energy storage technologies. However, the use of batteries as energy buffers is somehow problematic, since it is hard, if not impossible, to recover from rapid power fluctuations without dramatically reducing the batteries'' lifetimes. In a supercapacitor, energy storage is by means of static charge
A SC can withstand a deep discharge (a discharge of all the stored energy) unlike an electrochemical battery, so it has more efficient energy storage. Finally, a standard commercial SC can work in a wide temperature range (−40 to +60 °C) that can be largely extended for specialty applications.

Just 15 seconds can top the energy-charge off, and only a few minutes would suffice for a full charge. With frequent top-offs, it makes up for the lack of energy density and storage. And because Supercapacitors draw a lower current for a few minutes at a time, this puts less stress on the grid. Supercapacitors vs Lithium-ion Batteries
