Note that some other metals such as lithium and cobalt used in lithium-ion batteries are not rare earths. Where can you find "rare earths"? In reality, what makes them rare is the much-localized distribution of economically exploitable deposits, since the current quasi-monopoly concerns China for their extraction and transformation.

Despite this progress in using rare earth compounds for Li–S batteries, most work has centered on the cathode host and interlayer, with only a small portion covering lithium anode protection and electrolyte modification. In addition, the range of RE compounds selected as cathode hosts or interlayers remains quite narrow.

Rare earth doping in electrode materials The mostly reported RE incorporation in lithium/sodium battery is doping RE elements in the electrode. The lattice of the electrode material will be significantly distorted due to the large ionic radius and complex coordination of RE. Besides, this usually leads to smaller crystallites.
In this review, we try to look at the role of rare earths in inorganic solid lithium ion conductors. In the perovskite type, La is indispensable not only for its structure framing effects that make way for lithium ion transportation through a “bottleneck”, but also for its higher valence that results in numerous vacancies.
