E3 Lithium and Pure Lithium Build Lithium Metal Batteries Produced from Alberta Brines

CALGARY, Alberta–(BUSINESS WIRE)–$EEMMF #canadianenergy–E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3 Lithium” or the “Company,” a leader in Canadian lithium, is pleased to announce as part of its ongoing Joint Development Agreement with Pure Lithium Corporation (“Pure Lithium”) that the companies have produced lithium metal batteries using E3 Lithium’s brines and DLE technology and Pure Lithium’s innovative battery technology.

This initial work has focussed on integrating E3 Lithium’s concentrate production flow sheet with Pure Lithium’s proprietary Brine to Battery™ technology to produce high quality lithium metal batteries. Various versions of lithium chloride concentrate that reflect locations along the E3 Lithium process flow sheet have been electrodeposited into lithium metal and evaluated for consistency and purity. From there, batteries were produced to test how the metal performed when assembled into a battery. From this work, an optimized lithium chloride concentrate, in terms of lithium concentration and impurity profile, has been defined. E3 Lithium and Pure Lithium have successfully manufactured more than 80 lithium metal battery cells using lithium concentrate produced by E3.

Pure Lithium has proceeded with rigorous testing of the batteries for cell performance using industry standard metrics. An outline of the results from this work will be released once all the battery testing and analysis is complete.

“The production of lithium metal batteries from E3’s Alberta brine marks a significant milestone and outlines our ability to produce multiple battery grade lithium products,” said Chris Doornbos, President and CEO of E3 Lithium. “The successful integration of E3’s lithium brine resource and DLE technology with Pure Lithium’s innovative technology demonstrates our commitment to developing a secure, reliable, and local lithium battery supply chain.”

“The expertise of E3 Lithium’s team, along with their extensive brine resources, has been crucial in advancing our Brine to Battery™ technology for the production of lithium metal anodes,” said Emilie Bodoin, Founder, Chairman & CEO of Pure Lithium. “We are confident in our strong partnership with E3 and our shared ability to achieve large-scale lithium metal anode production at a fraction of current commercial costs.”

The testing program is expected to be completed in Q2 2025.

Equity Awards Grant

In relation to the Equity Awards Grant and Repricing of Options disclosed in the Company’s news release date March 7, 2025, the Board of Directors had also approved the issuance of an additional 300,000 restricted share units (“RSUs”) to the Company’s CEO, which RSUs will vest as to one third on each anniversary of the date of grant.
