Meet EC2 the world's most efficient, battery-grade lithium production process
The industry’s first and only all-in-one, fully integrated solution
EC2 is 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.
Meeting the needs of producers
EC2 is designed 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.
EC2 offers brine-based lithium producers, including geothermal and salar, an easily deployable, fully containerized solution optimized for a wide range of sources and concentrations, even in extreme locations.
alkaLi will introduce systems optimized to produce battery-grade lithium from evaporation ponds and battery recycling sources in late 2025—rapidly accelerating global lithium production.

CONCENTRATE
CFRO I receives the Li-rich stream and further refine to levels sufficient to convert 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.

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 a confidential client 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.
