Abstract
The resistivity of two types of lithium fast-ion conductors, Li16-2xZnx(GeO4)4 (x=1,2) and Li3+xGexV1-xO4 (x=0.25,0.6,0.72), showed pronounced maxima as a function of pressure. For the first type, ln(p/p0) peaked at values of 0.12 (x=1) and 0.35 (x=2) near 20 kbar and decreased thereafter up to 80 kbar. Thermal activation energies and prefactors also showed corresponding maxima. For the second type, ln(p /p0) increased to 3-4 between 20 and 32 kbar. Near 80 kbar, p decreased (for x=0.25) by a factor of 250. The results are interpreted in terms of negative activation volumes.
