应用领域

Sulfide-based solid electrolytes are essential components of advanced all-solid-state batteries as they exhibit the highest ionic conductivities. Argyrodite-structured sulfide solid electrolytes, like LPSClI, are among the most promising materials in this class and are currently the dominantly used solid electrolytes for all-solid-state battery fabrication. Argyrodite solid electrolytes are particularly appealing because of their ultrahigh Li-ion conductivity, quasi-stable solid–electrolyte interphase (SEI) formed with Li metal, and ability to be prepared via scalable solution-assisted synthesis approaches.PMID 34032414 The body-centered cubic-like anion framework present in LPSClI allows Li to hop directly between adjacent tetrahedral sites and facilitates the high ionic conductivity.PMID 26280225 In addition, iodine-doping improves the distribution of halogens over the sulfur sub-lattice, creating a structure with improved lithium diffusion kinetics. Because of its tailored composition, our battery grade I-doped lithium phosphorus sulfur chloride (LPSClI) is a high-performing material for solid-state battery research.
