Our Advantages
Electrochemical solution for an electrically driven future
Mangrove Lithium is a midstream electrochemical lithium conversion company that converts extracted lithium into a battery-grade product using electricity in place of chemicals.
By utilizing an electrochemical process, Mangrove removes the use of reagents, such as soda ash, lime and caustic soda, from the refining flowsheet. This advantage helps decrease the carbon footprint of the lithium supply chain, reduces the cost to produce a high-quality product, and eliminates the creation of any waste by-products, such as sodium sulfate, which carry a burden of disposal.
Mangrove's advantages and benefits
Mangrove provides a cost-efficient lithium conversion solution for upstream lithium producers, downstream battery manufacturers, and battery recyclers customers.
Electrochemical process removes use of reagents, such as soda ash, lime and caustic soda, reducing the cost of production and eliminating any waste by-product production.
Mangrove utilizes only electricity to drive its process and avoids significant carbon emissions by removing excess chemical transport associated with incumbent refining platforms. Mangrove can also be powered using renewable energy, compounding the environmental benefits.
Mangrove creates no waste by-products, including sodium sulfate. Incumbent lithium refining processes produce sodium sulfate waste that must be treated or disposed at a 2:1 ratio with the lithium hydroxide product.
Mangrove is feedstock flexible, converting lithium extracted from brines and, hard rock, battery recycling, and other. The platform is also product flexible, enabling the production of lithium hydroxide or lithium carbonate. This future proofs customers by allowing to adapt to evolving feedstock and battery material needs.
Added flexibility is supported through the electrochemical process that facilitates the ability quickly ramp up or down production at any given time.
Mangrove’s electrochemical technology unlocks higher yields of battery-grade lithium from various feedstocks. By utilising electricity to drive the refining process rather than introducing more chemicals, Mangrove can convert more feedstock into product more efficiently than incumbent systems.
In many cases, such as with lithium chloride from brines, Mangrove removes steps from the conversion flowsheet needed to produce battery-grade lithium hydroxide in comparison to conventional refining systems.
The only by-products produced in Mangrove’s electrochemical refining process are acids that can be recycled for use in upstream processing steps, creating circularity between refining and processing. For our beta-spodumene concentrate processing projects, Mangrove can recycle waste de-lithiated beta spodumene (DBS) for use as a supplement for cement manufacturing.
Mangrove’s patented Clear-Li<sup>TM</sup> lithium refining system requires less power than incumbent refining technologies to convert feedstock into a battery grade product.
Mangrove works along the battery-value chain with upstream miners, downstream battery/cathode manufacturers, and battery recyclers. This enables regional lithium refining capacity and brings conversion where it is needed most.
Mangrove’s patented Clear-LiTM electrochemical lithium refining technology uses a proprietary cell and process to efficiently convert extracted lithium for a variety of feedstocks into a battery grade lithium. In many instances, this technology and process allows Mangrove to be the most energy efficient, cost effective and sustainable refining solutions on the market.
Lithium Supply Chain
The global lithium supply chain is under pressure. While lithium reserves and production exist across continents, including North America, South America, Australia, and Africa, the vast majority of lithium refining is concentrated in China. According to Fastmarkets, China alone accounts for over 60% of global lithium refining capacity, creating a critical bottleneck in the battery value chain.
Wood Mackenzie’s analysis confirms that most lithium mined outside China is still shipped there for conversion into battery-grade products. This centralized refining model introduces significant risks:
- Geopolitical uncertainty
- Trade disputes
- Limited energy security
- Delayed time-to-market for battery manufacturers
In 2025, China’s Ministry of Commerce proposed export restrictions on lithium processing technologies, including those used to produce lithium salts and cathode materials like LFP and LMFP3. This move could severely impact Western companies that rely on Chinese expertise and partnerships to scale EV battery production.
In July 2025, China introduced new restrictions on the export of battery cathode material technologies, including processes for lithium-containing purification liquids and LFP/LMFP cathode preparation. These restrictions signal a tightening grip on critical battery technologies and raise concerns about future access for non-Chinese companies.
The Case for Regional Refining
Mangrove Lithium’s electrochemical platform offers a solution to these vulnerabilities by enabling domestic and regional lithium conversion. This shift unlocks several strategic advantages:
- Supply Chain Stability
Reduces dependence on foreign refining and mitigates exposure to geopolitical disruptions.
- Economic Value Capture
Allows lithium-producing countries to retain more value by refining locally rather than exporting raw materials.
- Energy Security
Strengthens national control over critical battery inputs, supporting clean energy and EV goals.
- Reduced Transport & Emissions
Co-location with miners, recyclers, and manufacturers minimizes long-haul logistics and lowers carbon footprints.
