Effect of Fe3+ doping on the structure and conductivity of LiTi2(PO4)3

Effect of Fe3+ doping on the structure and conductivity of LiTi2(PO4)3 Fe3+-substituted LiTi2(PO4)3 samples of composition Li1+x Ti2−x Fe x (PO4)3 (x = 0.0, 0.05, 0.1, and 0.15) have been prepared by solid-state reaction. XRD studies indicated formation of phase-pure materials of rhombohedral structure. Microstructural studies by scanning electron microscopy revealed particle size was in the micron range. Conductivity data at 533 and 573 K revealed increasing ionic conductivity with increasing dopant concentration. Electronic conductivity results correlated well with ionic conductivity. Cyclic voltammetry studies were indicative of electrochemical stability in the voltage range 0.5 to 3.5 V. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Fe3+-substituted LiTi2(PO4)3 samples of composition Li1+x Ti2−x Fe x (PO4)3 (x = 0.0, 0.05, 0.1, and 0.15) have been prepared by solid-state reaction. XRD studies indicated formation of phase-pure materials of rhombohedral structure. Microstructural studies by scanning electron microscopy revealed particle size was in the micron range. Conductivity data at 533 and 573 K revealed increasing ionic conductivity with increasing dopant concentration. Electronic conductivity results correlated well with ionic conductivity. Cyclic voltammetry studies were indicative of electrochemical stability in the voltage range 0.5 to 3.5 V.
