A facile method for the synthesis of the Li_0.3La_0.57TiO₃ solid state electrolyte

Abstract

We report a facile method for the synthesis of Li(0.3)La(0.57)TiO3 by forming a coagulated precursor solution which contains Li(+), La(3+), and TiO2 nanoparticles mixed highly homogeneously. The grain and overall conductivities of the synthesized Li(0.3)La(0.57)TiO3 are comparable to the values in literature for the material prepared by other methods.

Electric double-layer transistors: a review of recent progress

“…Since Inaguma et al reported high lithium ion conductivity (1 9 10 -3 S cm -1 ) in lithium lanthanum titanate at room temperature [153], research is focused on studying lithium ion conduction of La 2/3-x Li x TiO 3 (LLTO). In the LLTO structure, the lithium ions diffuse in a three-dimensional network of vacancy defects located at A sites perovskite and this conduction is based on hopping process [154]. The lithium ionic conduction of LLTO is influenced by A-site vacancy defects, lithium and vacancy concentration, structural distortion, bottleneck size, and Ti-O covalent bond [153,[155][156][157].…”

“…Afterward, Yanagi et al fabricated the Fig. 26 Schematic comparison of black phosphorus transistor [154] with other different transistors [30,31,[160][161][162][163][164][165][166][167][168][169][170].…”

Antiperovskite Li3OCl Superionic Conductor Films for Solid‐State Li‐Ion Batteries

“…Thus, the larger grain size would reduce the overall resistance, resulting in higher ionic conductivity. Furthermore, theoretical analysis has suggested that the nearest-neighbor Li-ion hopping favors along the edge of the Li 6 O octahedron via Li vacancies, [ 17 ] i.e., the (011) planes in the cubic antiperovskite structure. This provides further support for the higher conductivity of the fi lm with larger grain size and a preferentially orientated growth along (011).…”

“…In addition, the solid‐state electrolytes can be readily integrated with a metallic lithium anode, allowing solid‐state LIBs with potentially high energy densities. Thus far, solid‐state electrolytes have not been widely used in the commercial products because their ionic conductivities are not high enough to meet the requirements for high‐performance Li batteries . Hence, it is extremely important to develop advanced solid‐state electrolytes with high ionic conductivity and good compatibility with cathode and anode materials for all‐solid‐state LIBs.…”

Li-rich anti-perovskite Li3OCl films with enhanced ionic conductivity

“…Nevertheless, solid electrolytes have not been extensively used in lithium batteries because their ionic conductivities are still too low to meet the requirements for efficient electric-energy storage. [8][9][10] In addition, high interfacial resistance between the solid electrolyte and electrode is yet another challenge for solid-state LIBs.…”
