Lithium Lanthanum Titanium Oxide (LLTO)

Lithium Lanthanum Titanium Oxide (LLTO), with the general formula Li₃xLa₂/3-xTiO₃, is a ceramic material used primarily in advanced lithium-ion battery research due to its excellent ionic conductivity.

Physical Properties:

Appearance: Usually a white or pale-gray powder.

Phase: Typically synthesized as a ceramic material, allowing it to be formed into dense structures ideal for battery applications.

Thermal Stability: LLTO has good thermal stability, a necessary feature for solid-state battery applications that undergo varying thermal conditions.

Applications:

Solid Electrolytes in Batteries: Lithium Lanthanum Titanium Oxide is primarily used as a solid electrolyte in lithium-ion and lithium metal batteries, especially in next-generation all-solid-state batteries (ASSBs), due to its ionic conductivity and chemical stability.

Thin-Film Batteries: In thin-film battery applications, LLTO can be used to create dense electrolyte layers that separate the cathode and anode, providing a safer and longer-lasting battery.

Fuel Cells and Supercapacitors: Though its primary use is in batteries, Lithium Lanthanum Titanium Oxide is also explored for use in other energy storage and conversion devices like solid oxide fuel cells.

Lithium Lanthanum Titanium Oxide (LLTO) is a promising solid electrolyte material for advanced lithium-ion and lithium metal batteries, primarily due to its high lithium-ion conductivity, stability, and safety. Its applications are concentrated in the field of all-solid-state batteries, where it supports high energy density and long cycle life while mitigating safety risks associated with liquid electrolytes.
