While argyrodite sulfides are getting more and attention as highly promising solid-state electrolytes (SSEs) for solid batteries, they also suffer from the typical sulfide setbacks such poor electrochemical compatibility with Li anode high-voltage cathodes serious sensitivity to humid air, which hinders their practical applications. Herein, we have devised an effective strategy overcome these c...

The interfacial impedance of polycrystalline solid electrodes in the absence of Faradaic reactions is never purely capacitive; the deviation from ideal capacitive behaviour is usually larger on rough electrodes than on smooth ones. We present qualitative experiments to demonstrate that the frequency dependence of capacitance on solid electrodes is due to the atomic scale inhomogeneities rather ...

Solid-state flexible energy storage devices hold the key to realizing portable and flexible electronic devices. Achieving fully flexible energy storage devices requires that all of the essential components (i.e., electrodes, separator, and electrolyte) with specific electrochemical and interfacial properties are integrated into a single solid-state and mechanically flexible unit. In this study,...

Novel solid-contact iodide-selective electrodes based on covalently attached 1,2,3 triazole ionic liquid (IL) were prepared and investigated in this study. Triazole-based IL moieties were synthesized using click chemistry and were further copolymerized with lauryl methacrylate via a simple one-step free radical polymerization to produce a "self-plasticized" copolymer. The mechanical properties ...

All-Solid-State Batteries In article number 2300172, Ju Young Kim, Yong Min Lee, and co-workers present a dry pre-lithiation strategy for the graphite/silicon-based diffusion-dependent electrodes (DDEs) by simply introducing Li metal powder in DDE. The added uniformly continuously provides ions to active materials mitigates volume change of DDE during charge/discharge cycles, leading high-perfo...

Solid Electrolytes To develop electrolytes for high energy density solid-state batteries, in article number 2103049, Fang Lian and co-workers propose a novel “polymer-in-salt” solid electrolyte (PISE) via supramolecular interaction coordination between PME polymers LiPVFM/LiTFSI composite Li salts. The PISE possesses superior lithium ion transference number, ionic conductivity, excellent electr...
