Abstract
Perovskite-structured Li2x − ySr1 − xHf1 − yNbyO3 (x = 0.75y) solid state electrolytes with various Nb contents y = 0.25, 0.5, 0.75, 0.77 and 0.8 were prepared by conventional solid state reaction method at high temperature. Influence of compositions on structure and ionic conductivity of these perovskite-type ceramic electrolytes was studied. The crystalline structure, cross section microstructure, ionic conductivity and electronic conductivity were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), AC-impedance spectra and potentiostatic polarization experiment, respectively. All samples present perovskite structure. But impurity phases such as Nb2O5 and SrNb2O6 were detected. In this solid electrolyte system, a change from tetragonal perovskite structure to cubic perovskite structure was observed as the content of Nb was increased. Among these compositions, Li0.375Sr0.4375V0.1875Hf0.25Nb0.75O3 (V = vacancy) have the highest conductivity of σ = 2.91 × 10−5 S cm−1 at room temperature. Electronic conductivity for Li0.375Sr0.4375V0.1875Hf0.25Nb0.75O3 is negligible compare to its total conductivity. The interfacial electrochemical stability between Li0.375Sr0.4375V0.1875Hf0.25Nb0.75O3 solid electrolytes and electrodes was studied via cyclic voltammeter testing. Furthermore, all solid state Li battery Li/LSNH-3/LiNi0.5Mn1.5O4 were fabricated, but these batteries are unstable and could not operate. Li0.375Sr0.4375V0.1875Hf0.25Nb0.75O3 is unstable with metal Li, but it is stable when it is in contact with Li4Ti5O12 anode and high-voltage LiNi0.5Mn1.5O4 cathode.
