Summary: Hydride ion conductors, especially the fluorite-type LaH3-delta series, have shown high conductivity around room temperature. However, their non-stoichiometric nature poses challenges for their use as solid electrolytes. In this study, Sr-substituted LaH3-delta with slight O2- incorporation was synthesized, demonstrating H- conductivity at room temperature. This achievement is a significant milestone in the development of electrochemical devices that utilize its strong reducing ability.

Summary: This study presents an iodine-driven strategy to address the issues of insufficient ionic conductivity and low Li+ transference numbers in solid polymer electrolytes (SPEs). The introduction of electronegative iodine-containing groups effectively attracts Li+ ions, facilitates Li+ transport, and promotes the dissociation of Li salts. The iodinated single-ion conducting polymer electrolyte (IPE) demonstrates excellent ionic conductivity and Li+ transference numbers, as well as high stability in Li/Li cells and Li-S batteries, achieving high-capacity retentions when matched with intercalation cathode chemistries.

Summary: Li+-conducting solid electrolytes have attracted researchers' attention due to the development of efficient all-solid-state batteries. In this study, we propose a Mott-Schottky-based analysis to calculate the concentration of mobile Li+ in a lithium-conducting glass-ceramic. By using the space charge layer capacitances obtained from electrochemical impedance data, we can gain insights into the conductivity and temperature dependencies in ion conductors.

Summary: We developed solid-state hybrid electrolytes with single-ion conducting properties using binary core-shell polymer nanoparticles. By adjusting the size and number of nanoparticles, we created superlattices that optimized the concentration and transport of Li+. These electrolytes demonstrated exceptional ionic conductivity (10(-4) S cm(-1)), lithium transference number (0.94), electrochemical stability (up to 6 V), and modulus (0.12 GPa) at 25°C. When applied in Li-S batteries without liquids, they exhibited significant initial discharge capacity (1090 mA h g(-1) at 0.05C), long cycle life (over 200 cycles), and high rate capability (627 mA h g(-1) at 3C).
