High-safety and high-energy-density solid-state lithium metal batteries (SSLMBs) attract tremendous interest in both academia industry. Especially, composite polymer electrolytes (CPEs) can overcome the limitations of single-component electrolytes. In this work, a strategy combining rigid functional skeleton with soft electrolyte to prepare reinforced CPEs was adopted. The situ grown zeolitic imidazolate frameworks (ZIFs) three-dimensional cellulose fiber (ZIF-67@CF) succinonitrile (SN) plasticizer into poly(ethylene oxide) (PEO) together form ZIF-67@CF/PEO-SN CPEs. addition ZIF-67@CF SN PEO synergistically enhanced physical electrochemical properties Furthermore, conduction mechanism lithium-ion (Li+) studied using density theory. It is impressive that at 30 °C exhibit high ionic conductivity 1.17 × 10–4 S cm–1, competitive Li+ transference number 0.40, wide window 5.0 V, notable tensile strength 18.7 MPa, superior plating/stripping stability (>550 h 0.1 mA cm2). Such favorable features endowed LiFePO4/(ZIF-67@CF/PEO-SN)/Li cell discharging capacity (152.5 g–1 0.2 C), long cycling lifespan (>150 cycles 99% retention), operating safety. This work provides insights promotes application functionalized for SSLMBs.

Boosting the Ionic Conductivity of Pyrrolidinium-Based Ionic Plastic Crystals by LLZO Fillers

ACS Omega, Год журнала: 2024, Номер 9(20), С. 22203 - 22212

Опубликована: Май 9, 2024

Organic ionic plastic crystals (OIPCs) have attracted attention as novel organic solid electrolyte materials, but their insufficient mechanical strength and conductivity prevented application. In this study, a lithium salt, bis(fluorosulfonyl)amide (LiFSA), an inorganic electrolyte, Li7La3Zr2O12 (LLZO), were added to OIPC, N,N-diethylpyrrolidinium ([C2epyr][FSA]). The fabricated organic–inorganic hybrid electrolytes evaluated thermally, mechanically, electrochemically reveal which factors affect the properties of electrolytes. All samples showed excellent thermal stability regardless LiFSA or LLZO concentration, they found be highly ion-conductive solids at wide range temperatures. It was also revealed that addition raised nanoindentation stiffness (HIT) [C2epyr][FSA]/LiFSA composites. higher than pristine reaching value 2.1 × 10–4 S cm–1 25 °C upon appropriate amounts LLZO. Overall, with concentration moderate exhibited conductivity. Cyclic voltammetry results [C2epyr][FSA]/LiFSA/LLZO composites lithium-ion conductors. These findings indicate by optimizing concentrations salt LLZO, it would possible realize applications

Lithium-sulfur (Li-S) batteries are promising candidates for next-generation energy storage due to their high density, cost-effectiveness, and environmental friendliness. However, commercialization is hindered by challenges, such as the polysulfide shuttle effect, lithium dendrite growth, low electrical conductivity of sulfur cathodes. Cellulose, a natural, renewable, versatile biopolymer, has emerged multifunctional material address these issues. In anode protection, cellulose-based composites coatings mitigate formation improve lithium-ion diffusion, extending cycle life enhancing safety. As separators, cellulose materials exhibit ionic conductivity, thermal stability, excellent wettability, effectively suppressing effect maintaining electrolyte stability. For cathode, cellulose-derived carbon frameworks binders loading, active retention, resulting in higher density cycling This review highlights diverse roles Li-S batteries, emphasizing its potential enable sustainable high-performance storage. The integration into systems not only enhances electrochemical performance but also aligns with goals green technologies. Further advancements processing functionalization could pave way broader application battery systems.
