Product
Problem
Ultra-high-purity lithium (≥99.995%) is difficult to source in reliable, small quantities, limiting advanced applications in aerospace, semiconductors, solid-state batteries, and other next-generation technologies. Conventional chemical refining methods cannot consistently achieve the purity levels required for these demanding use cases.
Solution
Licube provides space-grade lithium carbonate (Li₂CO₃) and lithium hydroxide with purity of 4N5 (≥99.995%) through a single-pass electrodialysis process that uses Lithium Lanthanum Titanate (LLTO) solid electrolytes. The technology selectively passes lithium ions while removing impurities in one step, achieving purity levels unattainable with traditional refining. Licube has begun trial operations on a sample-scale production line capable of kilogram-scale output, with test runs underway to verify operational stability before formal sample shipments. The company is now accepting purchase indications from organizations across aerospace, semiconductor, energy, and medical sectors.
Target Audience
Licube's primary customers are advanced materials buyers in aerospace, semiconductor, optical crystal, solid-state battery, and pharmaceutical industries that require ultra-high-purity lithium for demanding applications.
