In Zn-based batteries, rare earths are employed to form cerium (Ce)-based oxide films on the Zn anode surface, which effectively mitigate GB corrosion .
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 compounds directly used as battery electrode material 2.3.1. Rare earth trihydrides Graphite is the mostly used anode for LIBs. The theoretical capacity of graphite is 372 mAh g −1 with voltage plateau around 0 V. It is desired that the capacity of anode would be larger with low voltage plateau.
In all kinds of energy storage devices, the most important component is the electrode. Therefore, discovering new electrode material and electrode modification have attracted most of attention of researchers. Rare earth (RE) is a group of VI elements comprised of metals from lanthanum to lutetium .
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.
Rare earth (RE) is a group of VI elements comprised of metals from lanthanum to lutetium . Yttrium and scandium are also usually considered as RE elements because they always appear together with other lanthanides in minerals . RE elements are abundant in the earth crust.
