Lithium is an essential resource used to manufacture cathode material for batteries. The growing demand for lithium hydroxide is mainly due to the manufacture of electric vehicles and the ongoing implementation of the new energy policy.
The number of electric vehicles is expected to rise to 30 million by 2030.
Lithium hydroxide is the raw material of choice for particularly high-performance cathode material materials, such as cobalt-reduced NMC 811.

The world’s largest lithium deposit is at Salar de Uyuni. Until now, it was not considered economically viable because it contains numerous magnesium salts.
In 2016, the Bolivian state enterprise YLB (Yacimientos de Litio Bolivianos) started to build large evaporation basins for a potassium chloride and lithium carbonate production plant at Salar de Uyuni. The first ones were put into operation two years later.
Through evaporation, a crude salt containing lithium sulfate is obtained which is used to produce lithium carbonate. The remaining brine contains a high proportion of magnesium, but also most of the lithium contained in the original salt solution. In the standard manufacturing process, the residual brine cannot be further processed and is therefore disposed of.
In cooperation with the Thuringian company K-Utec, ACISA has succeeded in obtaining high-purity lithium hydroxide directly from the residual brine. A major advantage of the developed technology is that no extra water is required. At the same time, the new process is comparatively inexpensive.
The contractually-guaranteed residual brine enables a yield of around 40,000 tons of lithium hydroxide per year. The entire project uses only 2% of the surface of Salar de Uyuni.
Production is due to start at the end of 2022.

To compensate for fluctuations in energy generation and supply, in the future photovoltaic and wind power plants will be equipped with lithium ion battery systems. These battery systems are also suitable for storing electricity in private households and companies.
Electromobility is the future. Rising numbers of electric vehicles and e-bikes are making their way onto the market. A positive environmental balance can only be achieved by producing batteries with "green" lithium.
Battery systems are becoming increasingly important as an independent and mobile source of energy for more and more everyday appliances. Household and garden tools, power tools, drones - nothing works without lithium ion batteries.

To industrialize lithium in Salar de Uyuni, ACI Systems Alemania andYLB have founded the joint venture YLB-ACISA E.M. The first task of this joint venture is to realize a production plant capable of yielding 40,000 tons of lithium hydroxide per year. At a later date, another joint venture is planned to manufacture cathode material and batteries.
Production capacity | 35 to 40,000 tons of lithium hydroxide per year |
Duration of the joint venture | 70 years agreed upon by contract – with guaranteed supply of the raw material |
