Lithium Titanium Oxide (Li₄Ti₅O₁₂), often referred to as LTO, is a highly stable and robust compound known for its use as an anode material in lithium-ion batteries. It has attracted attention due to its unique combination of properties, including high thermal stability, excellent cycle life, and low risk of overheating or fire.
Formula: Li₄Ti₅O₁₂.
Structure: Lithium titanium oxide has a spinel crystal structure, which provides excellent structural stability during the charge-discharge cycles in lithium-ion batteries.
Appearance: Typically a gray or dark-colored powder or crystalline solid.
Density: Approximately 3.5 g/cm³.
Particle Size: For use in batteries, it is often processed into fine powders to enhance its surface area and improve electrochemical performance.
Voltage: The nominal voltage of Lithium Titanium Oxide (Li₄Ti₅O₁₂) is around 1.55V, which is lower than other traditional anode materials like graphite but still provides excellent cycle life and stability.
Capacity: It has a lower theoretical capacity (about 175 mAh/g) compared to other anode materials like graphite (which has a theoretical capacity of around 372 mAh/g). However, it compensates with its high stability, fast charging, and safety characteristics.
Ionic Conductivity: Lithium Titanium Oxide (Li₄Ti₅O₁₂) exhibits relatively low electronic conductivity, but this can be enhanced by doping or combining it with other conductive materials.
Electric Vehicles (EVs): Lithium Titanium Oxide (Li₄Ti₅O₁₂) is used in some electric vehicle batteries, especially in situations where fast charging and safety are the top priorities.
Power Storage Systems: LTO is used in large-scale energy storage systems due to its long cycle life and thermal stability.
Portable Electronics: Though not as common as graphite-based anodes, LTO is being researched for use in portable electronics where safety and fast charging are important.
Military and Aerospace: The high safety, reliability, and performance of LTO make it suitable for use in applications that require high durability and long cycle life in harsh conditions.
