“…Solid-state reactions generally occur at higher temperatures and often lead to powder morphologies that are unfavorable for battery cell fabrication. In favorable cases, reactions can be carried out merely by grinding the reagents via mechanochemical synthesis 86 , and this method has been widely studied for the preparation of multinary fluorides. 41,51,56,70,[87][88][89][90] On the lab-scale level, such synthesis will be done with a high-energy milling method.…”

“…In a previously reported investigation about a SmF 3 synthesis, a conductivity jump for SmF 3 was found around 500°C, which corresponds to the orthorhombic (YF 3 )–trigonal (LaF 3 ) phase providing an elevated ionic mobility for the tysonite‐type network 15 . Recently, we reported that nano‐powdered Sm 0.95 Ca 0.05 F 2.95 material exhibits an ionic conductivity around 10 −5 S·cm −1 at RT 16,17 …”

Calcium fluoride solid electrolytes have been identified as a candidate for solid‐state fluoride‐ion batteries (FIBs). Here, we investigate the doping of CaF2 with samarium — Ca1−xSmxF2+x (0 ≤ x ≤ 0.15) — obtained by solid synthesis via high‐energy ball milling. Structural, morphological, and ionic conductivity studies of the as‐prepared materials were examined. It reveals that the fluorite‐type structure is dominating with a crystallite size of 12–14 nm. The highest ionic conductivity at room temperature had been obtained for Ca0.95Sm0.05F2.95 with a value of 2.8 × 10−6 S·cm−1. It proves that a small content of Sm doping can considerably improve the ionic conductivity of CaF2.

“…Preishuber-Pflügl and Wilkening gave a nice overview of local structures and ion dynamics in such defect-rich fluorides listed earlier [38]. Moreover, Patro very recently published an overview of the influence of milling process variables in a planetary mill on the synthesis and ion transport properties of fast fluoride ion conductors [59].…”

This lecture text is focused on the comparatively young field of mechanochemistry of fluoride solids, considering both their mechanical activation and their mechanochemical synthesis. Beside a literature survey, the mechanochemical synthesis of binary fluorides MF2, MF3, of complex fluorides MMgF4, of solid solutions MaxMb1−xF2 or M1−xLnxF2+x (Ln: Y, Eu) and of fluorine-containing coordination polymers is presented. Owing to their interesting potential applications in the field of fluoride ion conductivity or luminescence properties when doped, most of the given examples are alkaline earth metal compounds. A short historical survey, remarks on peculiarities and consequences of mechanical activation as well as the necessary technical equipment for mechanochemical reactions precede the section.
