Primary raw materials - LIB recycling

For the extraction of Li compounds, which are required in the form of different types of raw materials for numerous applications/products worldwide, we investigate and develop suitable processes for the extraction through to the processing of the resulting compounds, such as Li carbonate, Li hydroxide, etc., starting from potential sources (salt lakes or rocks). This includes research into the recycling of lithium-ion batteries.
