    Abstract
  • Ionic conductivity and activation volume of the bulk piece and powder of amorphous lithium ionic conductor B2O3-0.7Li2O-0.7LiCl-0.10Al2O3 were investigated in the hydrostatic pressure range from 0 to 2.21 GPa. For the hydrostatic pressure dependence of ionic conductivity of the bulk piece, a preliminary microscopic explanation was given by considering the physical picture of ionic transport passages. Effect of hydrostatic pressure on ionic conductivity of the amorphous powder consists of three changes in bulk-conductivity, contact-conductivity and boundary layer-conductivity with the same phase. Specially, the latter can increase the ionic conductivity 2.5~16 times. The experimental results show that there is a possibility of further enhancing the ionic conductivity for above material.
