Lanthanum Lithium Titanate (LLTO) sputtering targets engineered for depositing thin-film solid electrolytes used in next-generation lithium-ion battery research and production. As a perovskite-structured oxide prized for its exceptional bulk lithium-ion conductivity paired with near-zero electronic conductivity, LLTO enables safer, all-solid-state cell architectures that eliminate flammable liquid electrolytes. Each target is fabricated to a specified lithium content and purity grade, ensuring stoichiometrically faithful, pinhole-free films for demanding thin-film battery and microelectronic applications.
Lanthanum Lithium Titanate (LLTO), generally written as Li3xLa2/3-xTiO3, belongs to the A-site-deficient perovskite family, with Li, La, and vacancies sharing the A-site while Ti occupies corner-sharing TiO6 octahedra. Its vacant A-site pathways enable high lithium-ion conductivity, reaching approximately 10^-3 S/cm at room temperature, while its wide bandgap and low electronic conductivity make it an effective solid electrolyte. As a sputtering target, dense LLTO ceramic enables precise, uniform deposition of lithium-conducting films with controlled stoichiometry and thickness. Sputtered LLTO films are used in thin-film and all-solid-state batteries, lithium-dendrite-resistant interfaces, and advanced solid-electrolyte research.
Answer: La(1-x)LixTiO3 offers excellent thermal stability, high electrical insulation, and a tunable lithium content, making it suitable for thin-film applications in energy storage and electronic devices.
Answer: Store the target in a clean, dry environment to prevent contamination or degradation. Handle with care to avoid physical damage, and use gloves to minimize surface contamination.
Answer: Lanthanum Lithium Titanate is a perovskite material known for its high ionic conductivity. It is often used in solid-state batteries, sensors, and thin-film coatings.

Key Properties of Lanthanum Lithium Titanate
Property
Value
Significance
Crystal structure
Perovskite (ABO3-type), cubic/tetragonal/orthorhombic depending on x
A-site vacancy ordering defines the lithium-ion diffusion pathways through the lattice
Bulk Li-ion conductivity
~10^-3 S/cm at room temperature
Among the highest bulk ionic conductivities reported for any oxide solid electrolyte
Total (grain-boundary-limited) conductivity
~10^-5 S/cm at room temperature
Grain-boundary resistance is the primary bottleneck limiting practical device performance.
Electronic conductivity
Less than 10^-8 S/cm (electronic insulator)
Blocks electron transport so the film functions as a true single-ion (Li+) conductor
Density
~5.0 g/cm3 (theoretical, composition-dependent)
Used to calculate target mass, sputter yield, and expected film deposition rate
Varies with x, affecting stoichiometric control during target fabrication and film deposition
Thermal behavior
Decomposes rather than melts at high temperature
Permits high-temperature substrate deposition and post-anneal without target failure
Magnetic and optical character
Diamagnetic; wide bandgap (~3.5-4 eV)
Non-magnetic and largely transparent, compatible with multilayer optoelectronic and battery stacks
