The cathode contains the greatest variety of minerals, is the most valuable part of the battery, and is a major determinant in the performance of the battery—including the energy storage capacity, duration of charge, and battery lifespan.

By: Isaac Thornley | In 2023, the federal and Ontario governments pledged historic subsidies to automakers—up to $13.2 billion to Volkswagen, $15 billion to Stellantis—to build EV battery plants in Canada. While the subsidies show a commitment to secure a fully domestic supply chain for EV batteries, there remain significant gaps. These include a lack of mineral refining capacity in Canada, a lack of infrastructure in mineral-rich regions (such as the Ring of Fire), and, in particular, a lack of recognition of the jurisdiction of Indigenous peoples and their capacity to provide or withhold consent.
