Structural Characterization of Oxyhalide Materials for Solid‐State Batteries

Abstract: Development of materials with novel composition to obtain rechargeable solid‐state batteries with improved capacity and energy density is one of the hot topics in material science. Inorganic and thermally stable oxyhalide materials are potential substitutes for the toxic and flammable organic liquid electrolytes used in the Li‐ion batteries. Herein, Li‐, Na‐, and K‐ion‐based oxyhalide materials doped with Ca, Ba, and Mg are synthesized. The samples are characterized by neutron and X‐ray diffractometry, Raman s… Show more

“…Several approaches have been reported to date, including the use of polymers and ionic salts as well as formulations that include an inorganic solid conductor. , Futhermore, in ASSBs, the solid electrolyte membrane is required to act as both an electronic insulator and an ionic conductor, supporting highly stable lithium metal cycling, while avoiding lithium dendrite formation. A number of solid electrolyte options have been considered for ASSBs, including ceramic conductors (such as LLZO, LATP, sulfides, , oxyhalides, , etc. ), deep eutectic solvent (DES)-based self-healing polymer electrolytes, solid polymer electrolytes (SPEs), and composites (e.g., polymers combined with ceramics). In the class of SPEs, there are also several subclasses, for example SPEs consisting of a binary mixture of a polymer host and a lithium salt; polymers containing a low molecular weight plasticizer in addition to the lithium salt to enhance ion mobility; ionogels, where high content ionic liquid-based electrolytes are incorporated into a polymer network structure; and ternary systems, where the major components are the polymer and lithium salt, and ionic liquid (IL) is also included to further enhance conductivity …”
