Lithium battery production process diagram

Two Li compounds are typically used in the manufacturing of cathodes and anodes in battery cell production: Lithium Carbonate (Li2CO3), and Lithium Hydroxide (LiOH).

Both lithium carbonate and lithium hydroxide compounds are used in battery manufacturing. Lithium carbonate is used in LFP cathode chemistries for electric vehicles (EVs) and typically for energy storage systems (such as computers and cellphones). Lithium hydroxide is preferred in NMC or NCA cathode chemistries for EVs since they provide high energy density to batteries.

Lately, demand for both LiOH and Li2CO3 has been rising exponentially, causing prices to rise as the supply of viable, battery-grade lithium remains scarce. Mangrove works by to mitigate that supply pinch by converting raw Li sources directly into LiOH or Li2CO3 in fewer steps and with less OPEX than incumbent technologies.

Mangrove is not a direct lithium extraction company. Mangrove is a lithium conversion/refinery technology.

In essence, Mangrove converts Li extracted from raw sources (brines, hard rocks, geothermal, brine, clay, recycled batteries) into battery grade lithium (lithium carbonate and lithium hydroxide).

Our technology is modular, more cost effective, and feedstock flexible compared to incumbent operations. We can co-locate the conversion technology at any point of the battery value chain, eliminating the need to ship raw Li overseas for conversion into battery grade lithium. Our technology also eliminates other capital-intensive steps from the typical refining processes.

One of the most readily available and relied upon sources of lithium is from lithium brine deposits – saline ground water enriched with dissolved lithium. Mangrove Lithium can convert the lithium chloride extracted from the brines into lithium hydroxide and lithium carbonate  at high volumes and purity. However, there are several points that set Mangrove Lithium apart from typical lithium refining systems that convert brines:

  • Mangrove Lithium is able to directly convert lithium chloride from brine into lithium hydroxide for EV battery manufacturing. Incumbent technologies require lithium chloride be first converted into lithium carbonate, then into lithium hydroxide.
  • Mangrove Lithium is modular and can be co-located at any point of the battery value chain. Conversion can occur near the site of extraction, or near battery manufacturing. In most incumbent systems, raw lithium chloride from brine had to be shipped overseas for refining.

Mangrove works with partners  at all stages of the battery value chain. Because of the modular technology, Mangrove’s scalable platform can be co-located near the point of raw lithium extraction or near the site of battery manufacturing, eliminating the need to ship materials overseas to be refined. The patented, proprietary electrochemical technology also enables a wider range of feedstocks to be refined into high purity battery-grade lithium, providing a larger supply of lithium to meet the growing demand of EVs.

Mangrove is not a publicly traded company and stocks are not available for public purchase.

We use a patented proprietary electrochemical technology that converts a wider range of feedstocks directly into lithium hydroxide or lithium carbonate in fewer steps than incumbent refiners. Another important point of distinction is that our platform is modular and scalable. This means the technology can be easily co-located near the site of lithium extraction or near the site of battery manufacturing, eliminating the capital-intensive step of shipping lithium overseas for refining.

Ultimately, Mangrove is a mission-driven company; Mangrove seeks to build a more sustainable, electrified world by enabling faster and more sustainable adoption of lithium-ion batteries. The technology creates less waste product in the conversion process compared to exiting refiners – the by-product is a mild acid, which can be recycled in a closed-loop the extraction process.
