MAS NMR spectra. a, b 1H MAS NMR spectra of LiPAA/H2O electrolytes, the dashed lines indicating the shift of the “water” resonance to lower frequency (blue) and the sharpening of the CH2 resonance (red) as the water content increases. c 7Li MAS NMR spectra of the LiPAA/H2O electrolytes. All the LiPAA electrolyte spectra were acquired with a spinning rate of 14 kHz while the spectra of 1 M LiOH solution was measured under static condition
