Highlights: • Addition of the LBO glass enhance total ion conductivity up to four orders of magnitude. • Transport of Li{sup +} could be attributed to two media: grains and grain boundaries. • Sintering temperature is the most influential factor affecting the σ{sub tot}. • Melting of the LBO above 700 °C supports the sintering process. - Abstract: The LiTi{sub 2}(PO{sub 4}){sub 3} based composites containing amorphous Li{sub 3}BO{sub 3} were formed and investigated by means of X–ray diffractometry, thermogravimetry, scanning electron microscopy, impedance spectroscopy and density methods. The study shows that when a polycrystalline LiTi{sub 2}(PO{sub 4}){sub 3} material is sintered with Li{sub 3}BO{sub 3} glass, the resultant ceramics exhibit very high total ion conductivity. The maximum conductivity of 1.43 × 10{sup −4} S cm{sup −1} at 30 °C was achieved for the LTP–0.3LBO material sintered at 900 °C compared to 5.15 × 10{sup −8} S cm{sup −1} of the ceramic LiTi{sub 2}(PO{sub 4}){sub 3}.
