TG LATP Solid Electrolyte

Next-generation oxide solid electrolyte that satisfies both safety and cost-effectiveness

FOR YOUR

DREAM

Liquid electrolytes face thermal-runaway risks and energy-density limits, while sulfide electrolytes are difficult to commercialize due to extreme manufacturing requirements and very high costs. The only commercially viable answer that satisfies safety, process compatibility and cost-effectiveness at the same time is the oxide solid electrolyte.

Structure & Mechanism

■ Structural definition
Lithium aluminum titanium phosphate (chemical formula: Li₁₊ₓAlₓTi₂₋ₓ(PO₄)₃, LATP) is an oxide-based ceramic solid electrolyte belonging to the NASICON (Natrium Super Ionic Conductor) structural family.

■ Ion-conduction mechanism
In LATP, PO₄ tetrahedra and TiO₆ octahedra share corners to form a robust three-dimensional framework. This open framework provides continuous 3D ion-transport channels, enabling fast diffusion and migration of lithium ions.

■ Core competitiveness
This unique crystal structure is regarded as the fundamental basis that allows LATP to achieve high ionic conductivity.
