Halide Superionic Conductors for All-Solid-State Batteries: Effects of Synthesis and Composition on Lithium-Ion Conductivity

ACS Energy Letters, Journal Year: 2024, Volume and Issue: 9(5), P. 2212 - 2221

Published: April 15, 2024

Owing to their high-voltage stabilities, halide superionic conductors such as Li3YCl6 recently emerged promising solid electrolyte (SE) materials for all-solid-state batteries (ASSBs). It has been shown that by either introducing off-stoichiometry in solid-state (SS) synthesis or using a mechanochemical (MC) method the ionic conductivities of Li3–3xY1+xCl6 can increase up an order magnitude. The underlying mechanism, however, is unclear. In present study, we adopt hopping frequency analysis impedance spectra reveal correlations stoichiometry, crystal structure, conditions, Li+ carrier concentrations, migration barriers, and conductivity. We show unlike conventional made SS synthesis, mobile carriers defect-containing SS-Li3–3xY1+xCl6 (0 < x 0.17) MC-Li3–3xY1+xCl6 are generated with activation energy concentration dependent on temperature. Higher these samples arise from combination higher lower barriers. A new off-stoichiometric (Li2.61Y1.13Cl6) highest conductivity (0.47 mS cm–1) series discovered, which delivers exceptional cycling performance (∼90% capacity retention after 1000 cycles) ASSB cells equipped uncoated high-energy LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode. This work sheds light thermal process releases trapped ions halides provides guidance future development batteries.
