Abstract The political economy of lithium, a “critical mineral” for the renewable energy transition, is marked by two striking developments. First, Global North governments that have historically offshored mining are onshoring lithium to enhance “supply chain security.” Second, these committed “sustainably sourcing” lithium. In this article, I theorize both developments in terms novel security–...
