A unified theory of electrochemical energy storage: Bridging batteries and supercapacitors

https://techxplore.com/news/2022-03-theory-electrochemical-energy-storage-bridging.html

"binary view of electrochemical charge storage in nanoconfined spaces as either a purely electrostatic phenomenon, or a purely Faradic phenomenon... transition between the two determined by the extent of ion solvation and ion-host interaction... one end of the spectrum is a chemical bond—the basic mechanism of connection, a physical link at the atomic level. The other end is an electrostatic attraction that temporarily entraps ions within and on the surface of a material"
