Abstract
Lithium ion capacitors (LICs) are emerging as promising energy storage devices; thus, understanding their electrochemistry is of great interest. Here we report the study of a novel LIC by employing in situ nuclear magnetic resonance spectroscopy (NMR) as a nondestructive tool, revealing the sequence of electrochemical processes in it. We have performed in situ 7Li NMR experiments on the LIC by simultaneously cycling the LIC pouch cell in the voltage range 2.0
