Directing Ion Transport and Interfacial Chemistry in Pnictogen-Substituted Thio-LISICONs.

ABSTRACT: Aliovalent substitution is a ubiquitous strategy to increase ionic conductivity in solid-state electrolytes, often by many orders of magnitude. However, the structural and compositional changes that occur upon aliovalent substitution are highly interrelated, and a deep understanding of how substitutions simultaneously impact ion transport and the chemical evolution of interfaces during electrochemical cycling remain as prevailing challenges. Here, we interrogate aliovalent pnictogen substitution of Li₄GeS₄ in the series Li_3.7Ge_0.7Pn_0.3S₄ (Pn = P, As, Sb) and unravel the impact on ion transport processes and degradation during electrochemical cycling.
