"Rare earths" are a column (edit: ha ha see below) in the periodic table, and are not used in batteries.

Some types of electric motors use rare earths, others do not.

"Rare earths" are actually the lanthanides plus scandium and yttrium [1], not one column of the periodic table. Good information otherwise!
