Lithium Titanate (Li4Ti5O12) sputtering targets deliver the same spinel-structured lithium titanium oxide used as the anode-active phase in LTO lithium-ion batteries, formed into dense ceramic discs ready for thin-film deposition. Supplied by Infinita Materials, each target is fabricated from high-purity precursor powders and sintered to the density and grain structure needed for stable, reproducible sputter rates. The material’s near-zero lattice strain on lithium insertion makes it a preferred choice wherever researchers need to translate bulk LTO electrochemistry into thin-film form. Standard catalogue sizes ship from stock, with custom diameters, thicknesses, and bonded-target configurations available on request.
Lithium Titanate Li₄Ti₅O₁₂ crystallises in the cubic spinel structure (Fd-3m), providing a stable framework for reversible lithium-ion insertion with less than 1% volume change, giving it exceptional cycle stability. It is a wide-bandgap, electrically insulating oxide with good Li⁺ mobility and strong chemical and thermal stability. Because precise stoichiometry and nanometer-scale thickness are critical in thin-film battery architectures, RF magnetron sputtering from ceramic Li₄Ti₅O₁₂ targets enables dense, uniform, and composition-controlled films. These sputtered films are investigated as anode layers in thin-film and solid-state batteries, protective and interfacial buffer layers, and functional components in microelectronic energy-storage devices where low-strain lithium storage and long cycle life are essential.
Answer: Lithium Titanate is used as a sputtering target in producing lithium-ion batteries, particularly for anode materials and thin-film deposition in energy storage and electronic devices.
Answer: Li₄Ti₅O₁₂ offers high thermal stability, excellent cycling stability, and low toxicity, making it ideal for lithium-ion batteries and other energy devices applications.
Answer: Deposition typically occurs in a high-vacuum or inert gas environment, such as argon, using DC or RF sputtering techniques to ensure high-quality, uniform thin films.
Answer: Li₄Ti₅O₁₂ targets should be stored in a dry, clean environment to prevent contamination or degradation. Handling should be done carefully to avoid physical damage to the target surface.
