Two-dimensional layered lithium lanthanum titanium oxide/graphene-like composites as electrodes for lithium-ion batteries.

Perovskite-structured (ABO) lithium lanthanum titanate (LiLaTiO, LLTO) is widely used in all solid state lithium ion batteries due to its high ionic conductivity. In this study, a two-dimensional LLTO nanosheet/graphene (LLTO/C) nanosheet composite has been designed as an electrode material for lithium-ion batteries (LIBs). LLTO/C not only exhibits the ionic conductivity properties of perovskite-type LLTO, but the graphene between the layers of LLTO nanosheets also endows the material with additional electronic conductivity.
