Electrolytes play a vital role in the performance and safety of electrochemical energy storage devices, such as lithium-ion batteries (LIBs). While traditional LIBs rely on organic electrolytes, these flammable solutions pose risks require expensive, moisture-sensitive manufacturing processes. Aqueous electrolytes offer safer, more cost-effective alternative, but their narrow window, corrosivity to electrodes, enabling dendritic growth metal anodes limit practical applications. Water-in-salt (WiSEs) have emerged promising solution challenges. By significantly reducing water activity forming stable solid–electrolyte interphase (SEI), WiSEs can expand stability inhibit material dissolution, suppress growth. This unique SEI formation mechanism, which is similar that observed contributes improved WiSE-based batteries. Additionally, altered solvation structure minimizes presence free molecules, further stabilizing activity. review comprehensively examines composition, mechanisms, characterization application monovalent-metal-ion

Abstract The application of nickel‐rich layered oxide cathodes to sulfide all‐solid‐state batteries (SASSBs) is the most promising way achieve high capacity, energy density, and safety. However, disadvantages space charge layer, elemental diffusion, poor interfacial contact lead excessive impedance. Herein, a hybrid coating LPO LBO designed for NCM cathode with 95% Ni content. not only improves ionic conductivity Li + migration efficiency surface but also mechanical strength effectively mitigates stress–strain effect during long‐term cycling. SC‐NCM92@LPO+LBO||Li 6 PS 5 Cl||Li‐In SASSB delivers specific discharge capacity 220.5 mAh g −1 excellent high‐rate performance. SC‐NCM95@LPO+LBO||Li presents 253.3 performance (137.9 at 10C) cycling stability, maintaining its electrochemical under various conditions. This work provides valuable reference ultrahigh nickel‐layered in SASSBs.
