Licube’s Core Technology

Licube’s platform combines Electrodialysis (ED) with Lithium Lanthanum Titanate (LLTO) solid electrolytes, enabling both ultra-pure lithium production and isotope separation. As lithium ions selectively pass through LLTO, impurities are removed in a single step — achieving levels of purity unattainable with conventional chemical refining.

Because this separation is based on ion mobility, the same mechanism can be cycled repeatedly to distinguish even the slight differences between lithium isotopes. In other words, a single core technology enables both ultra-pure lithium compounds and lithium isotope enrichment, providing a unified path from advanced materials to fusion energy applications.

Some results have already been validated in peer-reviewed publications, while further advancements remain protected under patents and proprietary know-how at Licube.

Ultra-Fast & Ultra-Pure
Lithium Recovery

Conventional processes stop at battery-grade (99.5%). Licube’s three-electrode, dual-power-supply electrochemical pumping system selectively transfers lithium ions through LLTO, achieving extraction rates hundreds of times faster than conventional methods. This breakthrough makes large-scale, ≥99.99% LiOH production possible at competitive cost

Lithium isotope
separation (Li-6 / Li-7)

By exploiting the slight difference in ion mobility of lithium isotopes through LLTO under electrodialysis, Licube has demonstrated effective enrichment of Li-6 and Li-7. This scalable, mercury-free method provides a safe path toward isotopes for fusion energy and national security

Applications & Markets

Future-grade lithium opens up entirely new markets where performance and safety demand materials of the highest quality. Licube’s technology supports a broad range of frontier industries — enabling breakthroughs that would not be possible otherwise:

Space-Grade

Lithium hydroxide safeguards astronauts through CO₂ scrubbing in life-support systems and enables ultra-pure ceramics, shielding, and lightweight materials vital for spacecraft and satellites.

Fusion-Grade

Fusion-grade lithium refers to isotopically tailored materials that support peaceful nuclear fusion energy research and development.

Premium Battery Grade

Advanced energy storage systems demand specialty lithium compounds, where 4N purity ensures stability, safety, and long-cycle performance — essential for solid-state batteries, Li-S systems, aerospace, and next-generation mobility.

Semiconductor-Grade

Ultra-pure lithium meets the standards required for wafer cleaning, thin-film deposition, and specialty glass.

Pharma-Grade

High-purity lithium serves as a reagent in sensitive pharmaceutical synthesis, eliminating trace contaminants for safety and consistency

Assured-Grade

Lithium producers and DLE companies target battery-grade (≥99.5%), but variable feedstock makes consistency difficult. Impurity shifts push material off-spec, causing losses. Licube’s 4N lithium (≥99.99%) stabilizes output — blending it in secures reliable battery-grade compliance.

Racing-Grade

Racing-grade (Formula 1 / Formula E) lithium hydroxide enables maximum power density and thermal stability — giving Formula-class cars the speed edge in extreme conditions.

Products on Offer
