ONTARIO, 19 MARCH — A major battery materials project set to reshape North America’s electric vehicle (EV) supply chain is gaining momentum again, as Electra Battery Materials moves forward with construction of what is expected to become the continent’s only cobalt sulfate refinery.
The facility, located in Ontario, is designed to produce battery-grade cobalt sulfate, a critical component used in lithium-ion batteries powering electric vehicles and energy storage systems.
Once operational, the refinery is expected to play a central role in reducing North America’s reliance on overseas processing, particularly from China, which currently dominates global cobalt refining.
Construction Restart Signals Renewed Confidence
After a period of delays linked to financing constraints and volatile market conditions, Electra has restarted construction following the successful securing of fresh capital.
The company is now advancing structural work and key infrastructure installation, marking a significant milestone for the long-anticipated project.
Project Snapshot: North America’s Only Cobalt Refinery
Company: Electra Battery Materials
Location: Ontario, Canada
Investment: ~$80+ million secured
Status: Construction restarted
Completion Target: 2027
Output: Battery-grade cobalt sulfate
Significance: First refinery of its kind in North America
With construction activity ramping up, the refinery is now targeting mechanical completion by 2027, followed by a phased production ramp-up later that year.
Strategic Asset in the EV Supply Chain
Cobalt sulfate is an essential input in the production of high-performance EV batteries, particularly for nickel-rich chemistries widely used by automakers. Despite North America’s growing EV manufacturing base, the region has historically lacked domestic refining capacity for cobalt.
This project aims to close that gap.
By establishing a local processing hub, the refinery is expected to:
-
Strengthen supply chain security for battery manufacturers
-
Support regional EV production growth
-
Reduce dependence on imported refined materials
-
Align with government-backed efforts to build a resilient clean energy ecosystem
Reducing Dependence on China
Currently, a large portion of the world’s cobalt is mined in the Democratic Republic of Congo but refined in China, creating a bottleneck in the global battery supply chain.
The Ontario refinery represents a strategic move to diversify processing capacity and bring more value-added activities closer to end markets in North America.
Governments in both Canada and the United States have identified battery materials as a priority sector, with increased funding and policy support aimed at accelerating domestic capabilities.
A Turning Point for Battery Materials in North America
The progress of Electra’s refinery highlights a broader shift underway in the global energy transition — one where control over critical minerals and processing infrastructure is becoming as important as access to raw materials.
As construction continues through 2026 and beyond, the project is expected to attract attention from automakers, battery producers, and policymakers alike, all seeking to secure stable, transparent, and geographically diversified supply chains.
