Mangrove Lithium

Mangrove is a modular, scalable, electrochemical lithium refining platform that converts LiCl and Li2SO4 from a wide variety of feedstocks directly into battery-grade LiOH, eliminating complex and costly steps from conventional lithium processing companies.

The technology allows for continuous feeding of liquid lithium-containing feedstocks while outputting high-purity and high-recovery chemicals. It consists of strategically placed membranes and electrodes such that ions are moved from feedstock to product compartments when an electrical potential is applied to the cell. These electrochemical cells are both scaled in size and numbered up to result in a commercial scale throughput lithium refinery.

The electrochemical technology is fundamentally unique: the use of an oxygen/air cathode significantly reduces the voltage and energy consumption during the conversion process; a multi-compartment cell design allows for flexibility in terms of lithium feed concentrations and compositions; the need for managing concentrated chlorine or hydrogen is eliminated; and the design of the system simplifies the balance of plant, making it easier to manage and operate. Mangrove’s platform requires low CapEx and allows for lithium refining operations to be established near the point of feedstock extraction or near the site of battery manufacturing.
