Good news! None of those are used in batteries. In fact, there are no rare earth elements in batteries. Also, the article does not mention rare earths a single time. Even better: neodymium is unlike the other rare earths in that it is commonly found on its own. All the other rare earths almost always only occur together. Neodymium is quite easy to find an extract, and has always been of least/little concern. Back when fears about rare earth shortages were a thing, the element of concern was tellurium, as it was assumed that thin film cadmium-telluride solar panels were the next big thing. They are now virtually obsolete.
