They do not talk about this in electric car commercials.
However, Roskill also projects that, driven by rapidly increasing demand for neodymium-iron-boron (NdFeB) magnets (used in traction motors among other applications), neodymium will fall into deficit in 2016, although demand will initially be met by the drawdown of stocks. Roskill forecasts that the deficit will increase to 2021, making continued growth of NdFeB magnets unsustainable, despite efforts by rare earth producers to increase neodymium supply.

The neodymium price will rise towards the point of inflection, above which magnet consumers will begin to replace NdFeB magnet technologies with substitutes, Roskill says.
The green energy sector is the most vulnerable to price rises because of the large size of magnets used. Technologies already in use in this industry as an alternative to permanent magnet motors include induction motors in NEVs and induction/synchronous generators in wind turbines.
Roskill expects that by 2021 the high price of neodymium and concerns over supply availability will make projected growth rates of NdFeB demand unsustainable. Demand for NdFeB magnets will fall rapidly from 2022, before stabilizing at a much lower growth rate. Overall, NdFeB magnet growth between 2021 and 2026 is forecast to be flat, possibly falling by up to -1%/year.
