Advanced Functional Materials, Год журнала: 2024, Номер 35(1)

Опубликована: Окт. 31, 2024

Abstract The use of all‐solid‐state lithium metal batteries (ASSLMBs) has garnered significant attention as a promising solution for advanced energy storage systems. By employing non‐flammable solid electrolytes in ASSLMBs, their safety profile is enhanced, and the anode allows higher density compared to traditional lithium‐ion batteries. To fully realize potential solid‐state (SSEs) must meet several requirements. These include high ionic conductivity Li + transference number, smooth interfacial contact between SSEs electrodes, low manufacturing cost, excellent electrochemical stability, effective suppression dendrite formation. This paper delves into essential requirements enable successful implementation ASSLMBs. Additionally, representative state‐of‐the‐art examples developed past 5 years, showcasing latest advancements SSE materials highlighting unique properties are discussed. Finally, provides an outlook on achieving balanced improved addressing failure mechanisms solutions, critical challenges such reversibility plating/stripping thermal runaway, characterization techniques, composite SSEs, computational studies, ASS lithium–sulfur lithium–oxygen With this consideration, ASSLMBs can be realized.

Abstract Exploiting the synergy between organic polymer electrolytes and inorganic via development of composite can suggest solutions to current challenges next‐generation solid‐state lithium‐metal batteries (SSLMBs). Depending upon a mass fraction fillers polymers, are broadly classified into “ceramic‐in‐polymer” (CIP) “polymer‐in‐ceramic” (PIC) categories, inheriting distinct structure electrochemical properties. Since stability characteristics phase superior those for lithium‐ion conduction, applying lithium‐enrich active filler in PIC seems more promising. The preserves primary migratory channels electrolyte, while viscoelastic properties attempt be introduced from binder or host. present work overviews studies on state‐of‐the‐art electrolytes, fundamental mechanism ionic preparation methods, progress materials SSLMBs. In addition, modification strategies improving electrode–electrolyte interface also emphasized. Moreover, it further prospects effective future PICs‐based CPEs accelerate practical application This review examines outlook PIC‐based lithium batteries.

Lewis Acid–Base Synergistically Enhancing Practical Composite Electrolyte for Fluoride‐ion Batteries at Room Temperature

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Апрель 27, 2025

Abstract Fluoride‐ion batteries (FIBs) represent a potential “next‐generation” electrochemical storage device, offering high energy density. However, the practical implementation of FIBs at room temperature is impeded by limitations currently available ceramic electrolytes. Here, composite NH 4 HF 2 @PEO@β‐PbSnF electrolyte with both conductivity 10 −4 S cm −1 and wide stability window (4.59 V vs Pb/PbF ) fabricated. Field emission transmission electron microscope (FETEM) demonstrates presence space charge region, which enhances conductivity. Furthermore, 19 F NMR density functional theory (DFT) calculations elucidate that interaction between Sn 2+ (Lewis acid) − base) induces significant modifications to electronic structure, critically contribute enhanced electrolyte. Integrating this promising high‐voltage CuF cathodes anodes, reversible coin cell discharge capacity 143 mAh g up 50 cycles demonstrated. The rational design such electrolytes offers pathway toward application temperature.
