Abstract
LiSn2(PO4)3 anion was used to partially substitute for VO43– in the Nasicon compound of LiSn2(PO4)3via a sol-gel method. XRD analysis revealed that the LiSn2(PO4)3-substituted samples did not have a single LiSn2(PO4)3 phase, and some secondary phases like SnO2 and SnP2O7 appeared. Introduction of the LiSn2(PO4)3 anion did not prevent the LiSn2(PO4)3 compound from decomposing during the initial lithiation; however the LiSn2(PO4)3 anion substitution remarkably enhanced the rate capability and cycling performance of the products because they reduced the charge transfer impedance, increased the lithium ion diffusion, and strengthened the role of the Li3VO4 matrix due to the precipitation of the Li3VO4 phase. Of the substituted samples, the sample with a nominal composition of LiSn2(PO4)2.5(VO4)0.5 delivered a capacity of 449.2 mA·h/g at a rate of 0.25 C after 25 cycles and 373.8 mA·h/g at 2 C rate. Those values surpassed some previous reports on LiSn2(PO4)3 and the LiSn2(PO4)3/C composites. Accordingly, the partial substitution of phosphorus by vanadium in LiSn2(PO4)3 is a feasible technique to remarkably improve its electrochemical properties.
