Mangrove's Clear-Li uses electrochemistry to produce a pure lithium hydroxide for batteries

An electrochemical solution for lithium refining

Clear-LiTM is a patented electrochemical process for refining lithium sulfate and lithium chloride extracted from raw lithium feedstocks into battery-grade lithium hydroxide or lithium carbonate.
Whereas incumbent lithium refining processes rely heavily on chemical and energy inputs, Clear-Li uses electricity to produce battery-grade lithium. This yields a highly pure product at a lower cost and with less energy expenditure and smaller carbon footprint.

What is electrochemical lithium refining?

Mangrove’s Clear-LiTM electrochemical lithium refining technology uses an electrolysis process. This means we take lithium chloride from brines and DLE, and lithium sulfate from rock and clay deposits and use electricity to split these compounds and transform them into a highly pure lithium hydroxide. In the case of lithium chloride, hydrochloric acid is created as a byproduct. With lithium sulfate, sulfuric acid is produced as a byproduct. In both instances, these acids can be recycled for use in the lithium processing stage prior to refining.
