As global demand for electric vehicles, energy storage systems, and advanced electronics continues to accelerate, the race to secure critical battery materials has become a strategic priority for governments, manufacturers, and resource developers alike. A new research partnership between Sio Silica and the University of Manitoba could position Manitoba at the forefront of a breakthrough in silicon battery technology.
Last month, Sio Silica announced a strategic research partnership with the University of Manitoba’s Department of Chemistry aimed at advancing next-generation battery materials derived from Manitoba’s high-purity silica resources. The collaboration is focused on developing a mechanochemical single-step synthesis process capable of converting silica directly into silicon oxide-based anode materials for lithium-ion batteries, eliminating several of the costly and energy-intensive processing stages traditionally required in silicon battery production.
The research is being led by Dr. Christian Kuss, Associate Professor of Chemistry at the University of Manitoba, whose team is investigating a low-emission process that produces silicon suboxide nano-powders directly from high-purity silica without the use of harmful solvents or high-temperature furnaces.
“This partnership with the University is important to Sio,” explains Carla Devlin, President of Sio Silica. “Single-step silica processes allow battery anodes to be produced directly from high-purity SiO₂ rather than energy-intensive metallurgical silicon, reducing cost, complexity, and carbon footprint. This approach improves scalability, strengthens domestic critical-mineral supply chains, and supports high-capacity silicon-dominant lithium-ion battery performance. At Sio, we believe Manitoba can position itself as a world leader in value-added and engineered product supply chains built around high-purity silica.”
The technology has the potential to significantly improve battery performance while strengthening Canada’s domestic critical mineral supply chain. According to the research team, the resulting silicon-based anode materials could deliver six to ten times the lithium storage capacity of conventional graphite anodes, a development that could help extend electric vehicle driving ranges and improve energy storage efficiency. By utilizing Manitoba’s abundant high-purity silica as a feedstock, the project represents a potential pathway toward establishing a value-added battery materials industry in Canada while reducing the carbon footprint associated with conventional silicon processing methods.
The implications for battery manufacturing could be significant.
Silicon has long been viewed as one of the most promising materials for next-generation lithium-ion battery anodes because it can store substantially more lithium than conventional graphite. While graphite remains the dominant anode material used in today’s batteries, researchers worldwide are actively seeking alternatives that can improve energy density, charging performance, and battery lifespan. Silicon-based materials are increasingly seen as a key component of future battery technologies that will power electric vehicles, renewable energy storage systems, consumer electronics, and emerging industrial applications.
For Canada, the initiative highlights the growing importance of domestic critical mineral supply chains. Silicon was added to the U.S. Department of Energy’s Critical Materials List in 2023, reflecting its strategic importance to clean technology, semiconductors, solar energy, and advanced battery manufacturing. As North America works to reduce dependence on foreign supply chains, access to reliable domestic sources of battery materials has become a major strategic advantage.
Manitoba’s silica deposits are recognized for their exceptional purity and scale. Sio Silica’s project near Vivian, Manitoba hosts an estimated 15 billion tonnes of high-purity silica sand, making it one of North America’s largest known silica resources. Beyond traditional industrial uses, this resource has the potential to support high-value manufacturing applications ranging from solar panels and semiconductors to advanced battery materials.
Sio Silica’s broader vision extends beyond resource extraction. The company has consistently emphasized the opportunity to establish downstream processing and advanced materials manufacturing within Canada. By partnering directly with academic researchers, Sio is helping bridge the gap between mineral development and technological innovation, creating opportunities for value-added industries that can benefit both Manitoba and Canada’s broader economy.
The partnership also reinforces Manitoba’s growing role in Canada’s critical minerals ecosystem. As jurisdictions worldwide compete to establish secure and sustainable supply chains for battery materials, collaborations between industry and academia are becoming increasingly important. Manitoba’s combination of world-class silica resources, research expertise, supportive infrastructure, and access to North American manufacturing markets presents a compelling opportunity for future investment and innovation.
If successful, the University of Manitoba research program could transform a locally sourced Manitoba mineral into a key component of the batteries powering the next generation of electric vehicles and energy storage technologies. More importantly, it demonstrates how Canadian innovation can create value from critical minerals while supporting cleaner, more sustainable manufacturing processes and strengthening North America’s critical mineral independence.
As demand for battery materials continues to grow, projects that combine abundant domestic resources with cutting-edge research may become increasingly important to Canada’s economic and technological future. For Sio Silica and the University of Manitoba, the partnership represents an opportunity to showcase how Canadian science, innovation, and natural resources can work together to help power the energy transition.
