Mangrove’s benefits for battery recyclers

refining from Recycled batteries to meet the demand for lithium

Black mass processed from recycled batteries can be used to produce lithium sulfate, which in turn can be refined into lithium hydroxide for battery manufacturing

Circular lithium economy: creating an infinite supply of a finite commodity

Lithium, like most natural resources, is a finite asset that is removed from the earth in the form of hard rock, clays or brines. This means that if the renewable energy industry is to become truly sustainable it will have to harness the ability to recycle lithium from used batteries to continue to feed the demand.

Mangrove’s Clear-LiTM electrochemical lithium refining technology is able to take lithium sulfate or lithium chloride from recycled batteries and create a very pure lithium hydroxide or lithium carbonate efficiently and economically without creating any waste byproducts, creating a truly sustainable circular economy between battery production and disposal.

Benefits of Mangrove’s lithium refining technology for battery recyclers

  • No sodium sulfate waste byproducts:
    Mangrove’s Clear-LiTM electrochemical technology creates no sodium sulfate or other waste byproducts when refining lithium sulfate from hard rock and clay into lithium hydroxide. Incumbent lithium refining technologies produce sodium sulfate as a byproduct at a ratio with lithium hydroxide production of 1:2. This carries a burden of disposal, as sodium sulfate has very little commercial demand and requires proper disposal – adding to lithium production cost.
  • No chemical inputs mean a more pure product and no reliance on chemical suppliers:
    Because the Clear-Li electrochemical process uses electricity rather than chemical inputs, this allows Mangrove to refine a very pure lithium hydroxide. This is because the absence of chemicals eliminates the risk of contaminating the final product during the refining process. The absence of chemical inputs also means no reliance on chemical suppliers, eliminating the cost of a consumable and ensuring potential chemical supply-chain issues don’t risk refining operations.
  • Numbers up to scale with capacity:
    Mangrove's unique electrochemical cell/stack system is easily able to number up to meet the needs and capacity for projects of all sizes. The modular technology also has a smaller footprint than incumbent lithium refining systems.
  • Circular economy with recyclable H2SO4 byproduct:
    When refining lithium sulfate from hard rocks and clays to lithium hydroxide, Mangrove's refining technology only produces weak sulfuric acid (H2SO4) as it’s byproduct. H2SO4 can be reused at the lithium processing stage, creating a circular economy between extraction and refining.
