Energy Storage Using Supercapacitors: How Big is Big Enough?
Electrostatic double-layer capacitors (EDLC), or supercapacitors (supercaps), are effective energy storage devices that bridge the functionality gap between larger and heavier battery-based systems and bulk capacitors. Supercaps can tolerate significantly more rapid charge and discharge cycles than rechargeable batteries can.
ScienceDirect
Meanwhile, supercapacitors are always used as energy storage devices operating at high current rates. In this mode of operation, a large amount of heat is generated inside the battery due to electrochemical reactions and polarization, ohmic losses, and entropy changes during reversible charge-discharge processes [172] .
