Rapidly increasing the number of electric cars on the road in place of conventional cars is a key part of reaching net zero emissions by mid-century. At the same time, SUVs require larger batteries to power them, so a growing electric SUV market would impose additional pressure on battery supply chains and further increase demand for the critical minerals needed to make the batteries. Addressing those risks ahead of time is possible through a number of actions: downsizing of the average car size; increasing battery swapping; and investing in innovative battery technologies. Those strategies would keep in check the investment requirements for developing the cobalt, copper, lithium and nickel resources needed to satisfy the increasing uptake of EVs.
