This converts the lithium at the interface into lithium fluoride (LiF). It is important to note that the lithium atoms of the cathode material remain as ions, that is, as positively charged particles.

Fu Yuxi from Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences has developed the first room temperature holmium-doped yttrium lithium fluoride (Ho ...
