Electrical properties of La1.33−xLi3xTi2O6 (0.1<x<0.3)

High-Temperature Synchrotron X-Ray Powder Diffraction Study of the Orthorhombic–Tetragonal Phase Transition in La0.63(Ti0.92,Nb0.08)O3

“…A similar displacement was observed in the La (Ti ,Al )O compound (13), where Ti and Al atoms were found to displace 0.070 (8) This larger displacement is attributable to the larger charge of #5 for the Nb atom than those of #4 and #3 for the Ti and Al atoms, respectively. Such displacements have been observed also for La >V TiO \B (x(0.2) (11), La \V Li V TiO (30), La NbO (31), and La \V Li V Ti O (32). In the present re"nement the isotropic displacement parameter of La at the La1 site B(La1) was assumed to be equal to B(La2):…”

Study of the lithium insertion and de-insertion in perovskite praseodymium bismuth lithium titanate

“…16 and the increase in mobility for higher numbers of vacancies. 19 There is a high correlation between conductivity and diffusion in these materials, 18 but maximum conductivity is reached composition II 16 while the insertion is higher in composition I. The conductivity depends on the mobility (which in turn depends on the number of vacancies) and lithium concentration, and they are inversely proportional.…”

Quantum Chemistry in Proton-Conductors

“…For example, there is the inconsistency that the experimental activation energies for protonconduction in BaZrO 3 are very close to that for lithium ion-conduction in perovskite-type titanium oxide (around 0.4 eV), 57,58 in spite of the largely different operation temperature. Note that lithium ion-conduction occurs at room temperature.…”
