Lithium to nickel: Fueling clean energy and resilient industries
Canada’s critical minerals continue to power the technologies, infrastructure, and solutions driving a sustainable future. With abundant resources and growing capacity for value-added processing, Canada is well positioned to play a leading role in the global shift toward electrification and clean energy.
In this third installment of our alphabetical series for the Critical Minerals Review, we explore the next six critical minerals after indium—lithium, magnesium, manganese, molybdenum, nickel, and niobium. These materials are central to energy storage, manufacturing, and renewable technologies, underscoring Canada’s strategic advantage in the global critical minerals landscape.
Lithium: Powering the battery revolution
Lithium lies at the heart of today’s clean energy transition. A key component of lithium-ion batteries, it powers electric vehicles, consumer electronics, and grid-scale energy storage systems. Canada’s lithium potential, particularly in Quebec, Ontario, and Manitoba, is expanding through exploration and advanced processing projects that aim to supply North America’s growing battery supply chain.
With the EV market booming, lithium demand is projected to surge for decades. Beyond batteries, lithium compounds are used in air treatment systems, ceramics, and lubricants, demonstrating this mineral’s versatility in advancing modern life.
Magnesium: Lightweight strength for modern manufacturing
Magnesium, one of the lightest structural metals, combines low density with high strength, making it ideal for automotive, aerospace, and defense applications where weight reduction enhances energy efficiency and performance. Canada’s magnesium projects aim to support domestic and global supply chains for lightweight alloys used in vehicles, aircraft, and consumer electronics.
The mineral’s use in steelmaking and aluminum alloys also strengthens Canada’s manufacturing competitiveness, enabling producers to meet emission-reduction targets while maintaining high performance standards.
Manganese: Vital for batteries and steel
Manganese plays a dual role in Canada’s industrial and clean energy strategies. Traditionally used to harden steel, it now underpins the next generation of battery chemistries. High-purity manganese sulphate is emerging as a key precursor for electric vehicle batteries, particularly in nickel-manganese-cobalt (NMC) and lithium-manganese-iron-phosphate (LMFP) cathodes.
Canadian projects in New Brunswick and Quebec are positioning the country as a sustainable supplier of battery-grade manganese, aligning with national net-zero goals while revitalizing local economies.
Molybdenum: Strengthening alloys and energy systems
Molybdenum enhances the strength, corrosion resistance, and heat tolerance of steel and superalloys used in pipelines, turbines, and chemical plants. In Canada, molybdenum is often mined as a byproduct of copper operations, adding value to established resource networks.
Its role extends to clean technologies as well—molybdenum-based catalysts improve hydrogen production and environmental remediation processes, supporting the evolving hydrogen economy.
Nickel: The cornerstone of clean energy infrastructure
Nickel is essential for both stainless-steel production and advanced battery materials. High-purity nickel sulphate is critical for the cathodes used in electric vehicle batteries, offering high energy density and longer driving range. Canada’s nickel production—centered in Ontario, Manitoba, and Newfoundland and Labrador—plays a pivotal role in global supply chains for electrification.
Beyond batteries, nickel’s durability makes it indispensable in construction, water treatment, and aerospace applications. As demand rises for low-carbon, ethically sourced nickel, Canada is leveraging its strong environmental and social standards to secure its place in global energy transition partnerships.
Niobium: Supercharging strength and conductivity
Niobium, produced primarily from deposits in Quebec, is used to strengthen steel and superalloys, giving them superior resistance to heat and corrosion. These properties make niobium essential for jet engines, high-pressure pipelines, and infrastructure designed for extreme conditions.
Niobium’s growing importance extends into emerging technologies such as superconductors, quantum computing, and next-generation electronics, where its electrical properties support innovation and miniaturization.
From lithium’s role in electrification to niobium’s contribution to advanced manufacturing, these six minerals exemplify Canada’s capacity to lead in responsible resource development. Together, they form the building blocks of new energy systems, sustainable infrastructure, and high-performance technologies shaping the future.
