Griffin JM, Forse AC, Grey CP.
PMID: 26974032
Solid State Nucl Magn Reson. 2016 Apr-May;74:16-35. doi: 10.1016/j.ssnmr.2016.03.003. Epub 2016 Mar 04.

Electrochemical double-layer capacitors, or 'supercapacitors' are attracting increasing attention as high-power energy storage devices for a wide range of technological applications. These devices store charge through electrostatic interactions between liquid electrolyte ions and the surfaces of porous carbon electrodes....
