The structures of the samples were investigated using X-ray diffraction, Raman spectroscopy, and ³¹P nuclear magnetic resonance. The electrochemical properties of the samples were evaluated using cyclic voltammetry, direct current, and alternating-current electrochemical impedance measurements. The Li₇P₃S₁₁ solid electrolyte (SE) exhibited a Li⁺ conductivity of 1.5 × 10^-3 S cm^-1 at 25 °C. The electrochemical measurements confirmed that the synthesized electrolyte is a single Li⁺ conductor with stability up to 5.0 V <i>vs.</RSC advances33648-33656https://www.ebi.ac.uk/biostudies/studies/S-EPMC12435569biostudies-literatureSynthesis of Li&lt;sub&gt;7&lt;/sub&gt;P&lt;sub&gt;3&lt;/sub&gt;S&lt;sub&gt;11&lt;/sub&gt; solid electrolyte in ethyl propionate medium for all-solid-state Li-ion battery.PMC12435569Tu TAPhuc NHHfalseSynthesis of Li&lt;sub&gt;7&lt;/sub&gt;P&lt;sub&gt;3&lt;/sub&gt;S&lt;sub&gt;11&lt;/sub&gt; solid electrolyte in ethyl propionate medium for all-solid-state Li-ion battery.In this study, we report a facile wet chemical synthesis method for preparing Li₇P₃S₁₁ solid-state electrolyte using ethyl propionate as the solvent.
