Licube’s Core Technology

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

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

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.

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

Licube has begun producing 4N (≥99.99%) lithium hydroxide at pilot scale in Japan. Sample quantities are now available for partners to test and validate. A larger facility is under development, bringing tons-per-year production capacity online soon for commercial supply.
