摘要

For the first time, aniline was doped into the precursors used for preparing Li3V2(PO4)3, leading to apolyanilne (PANI)-doped Li3V2(PO4)3. In this work, three samples, having the weight content ofaniline 5 wt%, 7 wt% and 10wt%, respectively, were fabricated. The as-prepared samples werecharacterized by XRD, SEM, and FTIR, respectively. Unfortunately, the obtained XRD patterns ofpure Li3V2(PO4)3 is not very similar to the standard XRD patterns of Li3V2(PO4)3. But the XRDpatterns of the PANI-doped Li3V2(PO4)3 are consistent with standard XRD patterns of Li3V2(PO4)3 insome degree. SEM images strongly demonstrated that the weight content of aniline affected themorphologies of the obtained samples greatly, and it seemed that the sample with 7 wt % aniline hasthe smallest particle size among the obtained samples. Interestingly, the charge-discharge curvesrevealed that the PANI-doped sample of 7wt% aniline exhibited the largest discarge capacity amongthe three samples. The possible reasons for above phenomenon were well discussed based on the FTIRspectra and EIS measurement. Showing the sample of PANI-doepd Li3V2(PO4)3 is the maincontribution of this work, though unsatisfactory results were acquired.
