EV Batteries 101 and the Use of Nickel

By: Isaac Thornley | While the anode is mostly made from graphite, the cathode comprises a range of minerals such as lithium, nickel, manganese, and cobalt. 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.

The Biggest Gap in Ontario’s EV Battery Supply Chain: Indigenous Jurisdiction

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.

NEW REPORT: Greenwashing the Ring of Fire

By: Saima Desai and Isaac Thornley | The Ontario government is positioning the province as the home of a continuous supply chain for EV batteries. Their hope is that by securing Indigenous consent for mining in the North and massively subsidizing battery factories in the South, the difficult and dirty middle links of the supply chain—like extraction, transportation, and refining—will become inevitable.
