Graphitization Behaviors of Vapor-Grown Carbon Fibers with Different Diameters as Studied by Raman Spectroscopy

Abstract VGCFs have been used as the anode materials as well as conductive additives in Li-ion batteries due to these special chemical and physical properties. Three types of VGCFs with different diameter sizes from 10μm to 30nm were characterized by Raman spectroscopy to monitor the microstructure based on the size effect.
