Mass adoption of electric vehicles (EVs) is anticipated in the years ahead, driven primarily by policy incentives, rising incomes, and technological advancements. However, mass adoption is predicated on the availability and affordability of the raw materials required to facilitate this transformation. The implications of material shortages are currently not well understood and previous research tends to be limited by weak representation of technological change, a lack of regional disaggregation, often inflexible and opaque assumptions and drivers, and a failure to place insights in the broader context of the raw materials industries. This paper proposes a CoMIT (Cost, Macro, Infrastructure, Technology) model that can be used to analyse the impact of mass EV adoption on critical raw materials demand and forecasts that, by 2030, demand for vehicles will increase by 27.4%, of which 13.3% will be EVs. The model also predicts large increases in demand for certain base metals, including a 37 and 18-fold increase in demand for cobalt and lithium (relative to 2015 levels), respectively. Without major changes in certain technologies, the cobalt and lithium supply chains could seriously constrain the widespread deployment of EVs. Significant demand increases are also predicted for copper, chrome and aluminium. The results also highlight the importance of China in driving demand for EVs and the critical materials needed to produce them.
预计在未来几年,电动汽车(EV)将被广泛采用,这主要是由政策激励、收入增长和技术进步推动的。然而,大规模采用取决于促进这一转型所需原材料的可得性和可承受性。目前,人们对材料短缺的影响了解不足,以往的研究往往受到技术变革代表性不足、缺乏区域细分、假设和驱动因素往往不灵活且不透明,以及未能将见解置于更广泛的原材料行业背景中的限制。本文提出了一种CoMIT(成本、宏观、基础设施、技术)模型,该模型可用于分析电动汽车大规模采用对关键原材料需求的影响,并预测到2030年,车辆需求将增长27.4%,其中13.3%将是电动汽车。该模型还预测某些基本金属的需求将大幅增加,包括钴和锂的需求分别比2015年水平增长37倍和18倍。如果某些技术没有重大变化,钴和锂供应链可能会严重限制电动汽车的广泛部署。预计铜、铬和铝的需求也将大幅增加。结果还凸显了中国在推动电动汽车需求以及生产电动汽车所需关键材料方面的重要性。
