“All-solid-state batteries will require solid-state electrolytes and antiperovskites─materials adopting the perovskite crystal structure, but with cationic and anionic positions switched─look to be in the competition… or are they? In “Antiperovskite Superionic Conductors: A Critical Review” (DOI: 10.1021/acsmaterialsau.1c00026), Yiying Wu and co-workers from The Ohio State University take a deep dive into what these materials are, highlighting challenges in reproducibility, describing competing mechanisms of cation transport, and suggesting best practices for reporting functional properties. This is a must-read for anyone looking to investigate these materials for future applications (Figure 1).”-ACS Materials Au: Issue 2 Highlights and Call for 2022 Rising Stars (https://doi.org/10.1021/acsmaterialsau.1c00061)
