According to recent research from Changchun, People's Republic of China, "Polyethylene glycol (PEG, mean molecular weight of 10,000) has been used to prepare a Li3V2(PO4)(3)/C cathode material by a simple solid-state reaction. The Raman spectra shows that the coating carbon has a good structure with a low I-D/I-G ratio."
"The images of SEM and TEM show that the carbon is dispersed between the Li3V2(PO4)(3) particles, which improves the electrical contact between the corresponding particles. The electronic conductivity of Li3V2(PO4)(3)/C composite is 7.0 x 10(-1) S/cm. increased by seven orders of magnitude compared with the pristine Li3V2(PO4)(3) (2.3 x 10(-8) ...
