The origin of EV-crucial minerals
What minerals are used uniquely in the manufacture of electric
vehicles? Is the U.S. self-sufficient in these minerals, or does it
rely on imports? And if the latter, what are the source countries?
These questions are addressed in the two tables below.
Table 1 (top) lists the minerals used in a typical electric car
and a typical IC-engine conventional car. The data are from
the International Energy Agency [https://www.iea.org/reports/the-role-of-critical-minerals-in-clean-energy-transitions/executive-summary].
Importantly, they are applicable
for cars and not for vehicles in general, and they are not specifically
tailored to the cars made in the U.S. (Note that the
relative weight does not necessarily correspond to each mineral's
relative importance.)

REDEL introduces its latest plastic
High Voltage connector. These
2, 5 and 8 contacts configuration
are the ideal solution for industrial
applications.
The inherent safety, high voltage
specification (up to 10 kV AC),
lightweight design, and IP66 rating
make it an ideal candidate for
Industrial and Test/Measurement
segments and applications such as
automotive testing and electrical
cars.
