Ionic Conductivity of LiTi2(PO4)3-LiClO4 Composites

Composite solid electrolytes (1 - x)LiTi2(PO4)(3)-xLiClO(4) are synthesized and their conducting properties are studied. Heterogeneous doping of LiTi2(PO4)(3) with lithium perchlorate LiClO4 leads to a considerable increase of ionic conductivity and a decrease of activation energy as compared to the pure compound, which was not subjected to the pre-sintering. The conductivity of the composites reaches 6.8 x 10(-6) S/cm at 100 degrees C and 3.4 x 10(-4) S/cm at 200 degrees C with an activation energy of 0.62 eV.

Automated summary

Heterogeneous doping of LiTi2(PO4)(3) with lithium perchlorate LiClO4 significantly increases the ionic conductivity and decreases the activation energy of the composite material.
