Over the past decade, solid-state nuclear magnetic resonance (NMR) spectroscopy has emerged as a new probe of both the local chemical structure of EDLC electrodes, as well as their charge storage 50 mechanisms . NMR spectra of carbons saturated with electrolyte reveal separate resonances for "in-pore" ions (adsorbed in the carbon nanopores) and "ex-pore" ions (located outside the carbon pore network). The in-pore resonance appears at lower chemical shifts than the corresponding neat electrolyte due to the "ring currents" generated by the circulation of delocalized π-electrons in the aromatic carbon rings in the applied magnetic field . This effect is quantified by the Δδ value, 55 which is defined as: ∆𝛿 (𝑝𝑝𝑚) = 𝛿 )*+,-./ -𝛿 */12 /3/42.-352/ Where 𝛿 */12 /3/42.-352/ is the chemical shift of free electrolyte and 𝛿 )*+,-./ is the chemical shift of "in-pore" resonance.
