Model for the graphite electrode Interface analysis between a model for the graphite electrode and solvent for electrolytes of lithium-ion batteries. An example of the interface observation between highly oriented pyrolytic graphite (HOPG) as a model for graphite electrodes and tetraglyme, which has been studied as a solvent of electrolytes for lithium ion batteries. The AFM cantilever oscillation frequency and amplitude during the experiments were 92 kHz and 0.3 nm, respectively. The temperature was maintained at 298 K under an argon atmosphere throughout the experiment to prevent the dissolution of contaminants from the air, which could affect the interface structure. The topographic image revealed an ordered structure at Δf = 1000 Hz, obtained with tetraglyme adsorbed on an HOPG surface.
