The lithium supply chain faces structural constraints that limit the industry's ability to meet growing demand. Conventional lithium extraction methods recover just 25-50% of available lithium in a given source. The inefficacy of current methodologies is compounded by the associated costs and time: salar evaporation cycles stretch 18 months; hard-rock refining loses significant lithium capacity to process wastewater; and geographically isolated refining infrastructure causes supply chain bottlenecks, with EV & battery manufacturers absorbing those costs.
Demand is rapidly outpacing supply, but the solution is not finding new sources of lithium; it is enabling the ability to recover previously inaccessible lithium from existing resources. Without an efficient and sustainable brine-to-battery solution, the EV revolution will not sustain its growth.

Battery-ready Cathode
One membrane platform runs on salar brine, produced water, geothermal fluid, refinery wastewater, and low-concentration groundwater. If an aqueous source carries lithium, greenLi recovers it, at any concentration.
DCM builds battery-ready cathode materials, agnostic with any battery chemistry desired by manufacturers or consumers. As battery roadmaps shift, greenLi can shift with it, keeping our output aligned with market demand.
Containerized skids bolt on to existing operation infrastructure, deploying modularly using COTS parts. Extraction and cathode manufacture run on site, capturing margin across the full value chain.
Brine-agnostic. A continuous membrane platform that brings the proven economics of reverse osmosis desalination to lithium extraction, deployable on any aqueous source, at any concentration.
Unlike batch-process DLE technologies that cycle through adsorption and desorption phases, M.L.E. runs 24/7. No downtime for regeneration, no 18-month evaporation cycles. Just continuous throughput from feed to purified brine.
The platform ships in containerized skids that bolt onto existing infrastructure. Deploy at a salar, an oilfield, a geothermal facility, or a hard-rock refinery. No new factory required, no site-specific engineering from scratch.
The Li-selective membrane manufactures through established desalination supply chains. Scale-up does not depend on proprietary manufacturing. It leverages existing global capacity. Cost and lead times follow a well-understood learning curve.
Most lithium asset operators stop at carbonate or hydroxide, selling into a refining market where margins compress and dependencies sit outside their control. Traditional battery manufacture builds cathode structures around lithium as an input from centralized refiners.
Direct Cathode Manufacture (D.C.M.) is different. It converts purified lithium directly into battery-ready cathode powder on site, with no intermediate salts, no transport to a refiner, and no cathode chemistry lock-in. Operators capture the margin that today flows to cell manufacturers.
greenLi's platform deploys directly on salar operations and brine prospecting permits, recovering substantially more lithium from the same reserve volume. Operators gain more output from existing assets without expanding their footprint.
For spodumene refiners, M.L.E. captures the 20 percent of lithium currently lost to process wastewater. A new revenue stream recovered from what was previously a disposal cost, with no disruption to existing operations.
Oil and gas operators producing water from lithium-bearing formations can capture lithium as a co-product rather than paying for disposal. A meaningful new revenue stream added to an existing operation, without changes to the core business.
Geothermal plants and low-concentration groundwater assets can unlock lithium recovery for the first time. M.L.E. is the only extraction technology compatible with 60-degree Celsius return water and sub-50 ppm concentrations.
