A study by a team from MIT, with colleagues from Alfred University, UC Berkeley, and RIT, has found that supplies of cobalt—a critical material in some battery chemistries—is adequate in the short-term (up to 2030), but that the industry needs to invest in additional efficient refining and recycling capacity, so it can continue to meet demand. The paper is published in the ACS journal Environmental Science & Technology . Roughly 60% of mined cobalt is sourced from the Democratic Republic of Congo (DRC). The element is often recovered as a byproduct from mining copper and nickel, meaning that demand and pricing for those other metals affects the availability of cobalt. Half of the current supply of cobalt is incorporated into cathodes for lithium-ion batteries, and many of those batteries are used in consumer electronics and electric vehicles. Demand for these vehicles and their batteries is growing swiftly: In 2018, […]
