Lithium Titanium Oxide (LTO) Sputtering Target is a specialized material primarily used in the production of thin films for energy storage devices, such as lithium-ion batteries. Lithium titanium oxide, specifically the compound Li₄Ti₅O₁₂, is known for its stability and excellent cycling performance, making it a popular material in battery anodes.
When used as a sputtering target, LTO enables the deposition of thin, uniform films of lithium titanium oxide, contributing to the development of advanced battery technologies and electronic components.
Formula: Li₄Ti₅O₁₂ is the most common form, though variations may exist depending on specific application requirements.
Structure: Lithium Titanium Oxide has a spinel crystal structure, which contributes to its excellent stability during cycling in battery applications and its ability to maintain structural integrity.
Appearance: Typically a gray or off-white ceramic-like material in its bulk form.
Density: Approximate density ranges from 3.4 to 3.6 g/cm³, which may vary slightly depending on purity and processing.
Hardness: Being a ceramic-based target, Lithium Titanium Oxide is relatively hard and brittle, which necessitates careful handling and mounting during the sputtering process.
Thermal Stability: Lithium Titanium Oxide is stable at high temperatures, which allows it to withstand the energy-intensive sputtering process.
Electrical Conductivity: Although LTO itself is not highly conductive, its electrochemical stability is advantageous in battery applications where it provides a stable structure for lithium-ion insertion and extraction.
Chemical Stability: Lithium Titanium Oxide is chemically stable and resists reactions with the electrolyte in lithium-ion batteries, reducing the risk of side reactions that degrade performance.
Lithium-Ion Battery Anodes: Thin LTO films deposited via sputtering are used as anode materials in lithium-ion batteries. LTO anodes are known for their stability, low volume expansion during charging/discharging, and long cycle life, making them ideal for high-performance batteries.
Thin Film Batteries: In thin film batteries, LTO sputtering targets help create compact and efficient energy storage devices for microelectronics and wearable devices.
Electrochemical Capacitors and Sensors: LTO films can also be used in electrochemical capacitors or as a component in sensors, where the stable cycling and structural properties are beneficial.
