Lithium Ion Conducting Solid Electrolyte Lanthanum Lithium Titanate (LLTO)
(Toho Titanium Co., Ltd.)
The LLTO crystal has a perovskite structure and is chemically very stable. In the future, it is expected to be applied to multi-layer solid state batteries and large cells for EVs. Low-temperature sintering and reduced resistance are key points in realizing co-firing with cathode and anode active materials as shown in the figure below. Toho Titanium is developing ways to meet these challenges.

What are the features of LLTO?
High ionic conductivity and stability in the atmosphere.
LLTO is classified as an oxide solid electrolyte.
Among such electrolytes, it exhibits a relatively high ionic conductivity (bulk) of 10-3 S/cm.
In addition, it is a stable compound and does not react with moisture in the atmosphere.
