“…In the meantime the compounds have attracted some attention as fast solid lithium ion conductors [3][4][5][6]. More recent investigations in these systems elucidate structures and structural relationships of compounds that can be described with the general composition Li 3-2y N 1-y X y with X = Cl, Br, I [7][8][9][10][11][12][13][14][15].…”

Abstract. The compounds Li 8 EN 2 with E = Se, Te were obtained in form of orange microcrystalline powders from reactions of Li 2 E with Li 3 N. Single crystal growth of Li 8 SeN 2 additionally succeeded from excess lithium. The crystal structures were refined using single-crystal X-ray diffraction as well as X-ray and neutron powder diffraction data (I4 1 md, No. 109, Z = 4, Se: a = 7.048(1) Å, c = 9.995(1) Å, Te: a = 7.217(1) Å, c = 10.284(1) Å). Both compounds crystallize as isotypes with an anionic substructure motif known from cubic Laves phases and lithium distributed over four crystallographic sites in the void space of the anionic framework. Neutron powder diffraction pattern recorded in the temperature range from 3 K to 300 K and X-ray diffraction patterns using synchrotron radiation taken from 300 K to 1000 K reveal the structural stability of both compounds in the studied temperature range until decomposition.

“…They have many advantages compared to liquid or polymer based electrolytes such as high electrochemical stability with favorable anodes and cathodes, no leakage, flexibility in cell design and possible high operational temperature [ 1,2]. Among the various structural families of solid state lithium ion conductors [3][4][5][6][7][8][9], perovskite (ABO3) based electrolytes have attracted much attention in recent years. A high bulk lithium ion conductivity of about 1.0 x 10 .3 S/cm at room temperature has been reported for lithium-lanthanum-titanate (LLT) [10,11].…”

Abstract. We report the synthesis and lithium ion conductivity of di-, tri-, tetra-and hexavalent metal ion B-site substituted (Li,La)TiO3 (LLT) perovskites. All 5-10 mol% Mg, A1, Mn, Ge, Ru and W ion substituted LLTs crystallize in a simple cubic or tetragonal perovskite structure. Among the oxides investigated, the Al-substituted perovskite La0.55Li0.361"10.09Ti0.995A10.00503 (1"1 = vacancy) exhibits the highest lithium ion conductivity of 1.1 x 10 -3 S/cm at room temperature which is slightly higher than that of the undoped (Li,La)TiO3 perovskite (8.9 x 10 4 S/cm) at the same temperature. The lithium ion conductivity of substituted LLTs does not seem to depend on the concentration of the A-site ion vacancies and unit cell volume. The high ionic conductivity of A1-substituted LLT is attributed to the increase of the B(A1)-O bond and weakening of the A(Li,La)-O bond. The conductivity behavior of the doped LLT is being described on the basis of Gibbs free energy considerations.

“…Thus the possible application of binary lithium nitride as a solid state electrolyte at elevated temperatures is limited. In order to compensate for this disadvantage several ternary lithium nitrides have been investigated and their lithium ion conductivity has been measured [2][3][4][5][6]. Aiming at a practical use of the compounds, ternary lithium nitrides containing the main group elements boron, aluminum, and silicon have been of particular interest [2][3][4].…”

Single phase lithium phosphorus nitrides LiTPN4 and LiPN2 were prepared by reaction of the binary nitrides P3N5 and Li3N at 620 and 800 ° C, respectively. The compounds were identified by X-ray powder diffraction techniques. The lithium ion conductivity of both compounds was investigated by complex impedance spectroscopy in the temperature range between 50 and 350 ° C. The specific conductivity was found to be 0(400 K) = 1.7× 10 -5 and 6.9× 10 -7 f~-t cm-~ for Li7PN4 and LiPN2, respectively. The activation energy was 46.7 kJ/mol for Li7PN4 and 58.9 kJ/mol for LiPN2.
