摘要：

The LiTi2(PO4)(3)-based ceramic composites with addition of Li2.9B0.9S0.1O3.1 (LBSO) were formed and investigated by means of X-ray diffractometry, thermogravimetry, scanning electron microscopy, impedance spectroscopy and density methods. Significant enhancement of total ionic conductivity of the formed composites could be observed after sintering the material at high temperatures. The maximum conductivity of 1.79 x 10(-4) S.cm(-1) at 30 degrees C was achieved for the LTP-0.3LBSO material sintered at 900 degrees C compared to 5.15 x 10(-8) S.cm(-1) of the ceramic LTP.
