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 10 mu m to 30nm we
re characterized by Raman spectroscopy to monitor the microstructure based
on the size effect.
