摘要

This study was focused on enhancing the conductivity of lithium tin phosphate, LiSn2P3O12 by4+ 3+ partially substituting Sn ions with Cr ions to obtain system with general formula Li1+xCrxSn2- xP3O12. Li1+xCrxSn2-xP3O12 powders with x = 0.2, 0.4, 0.6 and 0.8 were prepared by mechanochemicalmilling method. X-ray diffraction analysis indicated that all samples consisted of triclinic crystalline3+ LiSn2P3O12 structure. Energy Dispersive X-ray analysis suggested that Cr was successfullysubstituted into the LiSn2P3O12 crystalline structure. Impedance analysis showed an increase inconductivity with increase in x. The enhancement in bulk conductivity was due to increase in number+ and polarisability of Li ions and crystallinity. The increase in grain boundary conductivity was+ ascribed to enhancement in Li migration as a result of increase in contact between grains. Theconductivity versus the reciprocal of temperature plots showed a sudden change in conductivity at 393K for the sample with x = 0.2 and 373 K for the sample with x = 0.4, 0.6 and 0.8. This was attributed toa structure transition phenomenon. All samples showed Arrhenian behaviour.
