E3 Lithium and Pure Lithium Achieve Breakthrough in Sustainable Battery Technology
CALGARY, Alberta—E3 Lithium Ltd. (TSXV: ETL; FSE: OW3; OTCQX: EEMMF), a pioneer in lithium development, today unveiled promising initial results from its collaborative battery cell testing program with Boston-based Pure Lithium Corporation. The advances center on the integration of E3 Lithium’s brine-derived lithium chloride and proprietary Direct Lithium Extraction (DLE) technology with Pure Lithium’s next-generation metal anode and battery manufacturing processes.
Under a Joint Development Agreement announced earlier this year, multiple lithium chloride samples extracted from E3’s Alberta-based brines were processed by Pure Lithium into battery-ready anodes using its innovative electrodeposition technique. These anodes were then assembled into functional batteries and subjected to rigorous performance testing. Key outcomes include:
- Purity Benchmarks: All E3 lithium samples exceeded 99.9% purity as validated by ICP-OES analysis—a critical threshold for high-performance battery applications.
- Cycle Life: Batteries retained over 80% capacity after 500 charge-discharge cycles, signaling competitive longevity for electric vehicles and grid storage systems.
- Rapid Charging: Tests conducted at a 1C:1D rate (full charge/discharge in one-hour intervals) demonstrated the technology’s compatibility with fast-charging demands.
The study identified an optimal brine processing pathway within E3’s commercial-scale design that minimizes production costs while maintaining performance parity with conventional lithium sources. Both companies now focus on scaling an integrated system to mass-produce cost-efficient, high-purity lithium metal anodes—an innovation that could streamline the green energy supply chain.
“This partnership validates Alberta’s potential as a global lithium hub,” said Chris Doornbos, CEO of E3 Lithium. “By combining our resource expertise with Pure Lithium’s groundbreaking battery tech, we’re delivering solutions that marry economic viability with cutting-edge performance.”
Pure Lithium CEO Emilie Bodoin emphasized the disruptive potential: “We’ve redefined lithium processing by eliminating reliance on traditional mining. Our Brine-to-Battery™ approach not only bypasses nickel and cobalt but demonstrates that non-conventional lithium sources can power tomorrow’s energy storage systems.”
Strategic Significance: E3 Lithium controls over 16 million tonnes of measured and indicated lithium carbonate equivalent (LCE) across Alberta and Saskatchewan, including a definitive 1.13 Mt LCE reserve at its Clearwater project. A recent pre-feasibility study projected a $5.2 billion pre-tax NPV for Clearwater, positioning the company as a potential top-tier supplier in North America’s battery metals sector.
Market Outlook: The collaboration taps into surging demand for domestically sourced critical minerals, aligning with U.S. and Canadian initiatives to reduce reliance on foreign lithium supply chains. Pure Lithium’s graphite- and cobalt-free battery design further addresses supply risks and sustainability concerns plaguing traditional lithium-ion technologies.
Forward-Looking Disclosures: Statements regarding future production timelines, resource estimates, and financial projections involve risks including fluctuating commodity prices, regulatory approvals, and technological scalability. Detailed risk factors are disclosed in E3 Lithium’s filings on SEDAR+.
