Introducing
powered by EC2
The World's Most Efficient, Battery-Grade
Lithium Production Process
alkaLi is a standalone company, spun out from Gradiant, dedicated to accelerating the scaling of battery-grade lithium production.
Powered by EC2, the industry’s first and only all-in-one, fully integrated solution, engineered to EXTRACT, CONCENTRATE, and CONVERT battery-grade lithium.
alkaLi offers the world’s most efficient solution to produce lithium and meet the rapidly growing trends in electrification—led by the demand for EVs, energy storage, and portable devices.
We are now onboarding customer partners.

Meeting the needs of producers
Gradiant has designed EC2 to be highly modular, with a balanced system that can be adapted to a broad range of source inputs, enabling it to meet the industry’s evolving demands.
alkaLi will offer the technology to brine-based producers, including geothermal and salar, in an easily deployable, fully containerized solution optimized for lithium production from a wide range of sources and concentration levels, even in extreme locations.
alkaLi will also deploy systems optimized to produce battery-grade lithium from evaporation ponds and battery recycling sources—rapidly accelerating global lithium production.
This groundbreaking technology offers producers compelling benefits:
World's most effective DLE
Delivering industry-leading Generation II lithium concentrations
Fully integrated, balanced system
All-in-one engineering optimized for highly varied input conditions
Instantaneous production
With battery-grade output measured in seconds, not years

EC2 is Gradiant-Grade Innovation at its best
Built on proven technologies with material science expertise from the Gradiant Labs, EC2 is a balanced three-stage system adaptable to a broad range of sources—including geothermal brine, evaporation ponds and recycling. Each stage has been thoroughly tested through bench and field trials, with a successful commercial proving in partnership with SLB at their Nevada site. To satisfy the exacting requirements of lithium producers, the EC2 solution can be deployed in full or as standalone stages, integrated with existing site infrastructure.

CONCENTRATE
CFRO I receives the Li-rich stream and further concentrates to levels sufficient to refine to battery-grade to flow to the Convert Stage.
CFRO II receives the Li-lean stream and reduces TDS to below regulatory limits, allowing expedited permitting and discharge-ready water.
