AC impedance spectrum analysis of the intercalation mechanism in HCOOH-GIC formation
A.c. impedance spectroscopy was used to analyze the electrochemical intercalation of formic acid (HCOOH) into graphite. The results show that the formic acid intercalation reaction is just a process of charge transfer, adsorption and diffusion of intercalate.
