Stabilizing Lithium-Oxygen Batteries through In Situ Generated Phenyl/LiF-Rich Hybrid SEI Layer with Sulfonyl Fluoride Electrolyte Additive

“…Then added N-methyl-2-pyrrolidone (NMP) to the mixture. Ultrasonicated the mixture for 30 min and stirred on a magnetic stirrer for 24 h. The Characterization.-The lithium-oxygen batteries were disassembled in an Ar-filled glove box, the Li anodes used for characterization were removed and cleaned in DME for 30 min and dried for 30 min, 26,27 and the microstructures of the lithium anodes were observed using a field emission scanning electron microscope (SEM, Apreo 2 C). The elemental mapping information of the Li anode was determined by energy dispersive spectroscopy (EDS) and scanning electron microscopy.…”

Computational approach inspired advancements of solid-state electrolytes for lithium secondary batteries: from first-principles to machine learning

“…Conversely, the oriented ferroelectric polarizations of the KNN layer significantly weaken the sharp potential drop and suppress the growth of the solid–electrolyte interphase (SEI). Similarly, a sandwich-structured ceramic-gel CE, 246 and a composite interface composed of the mechanically robust Li y Sn alloy and the ion-conducting Li 3 N, 247 were proposed for use in Li batteries. In this configuration, a GPE modification layer was coated on both sides of the SIE.…”

3D Flexible Electrospun Nanocomposite Polymer Electrolyte Based on Li1.45Al0.45Ge0.2Ti1.35(PO4)3 for Lithium Metal Batteries

“…In the composite polymer electrolyte, ceramic filler nanoparticles can be differentiated into nonlithium-ion conductive fillers like Al 2 O 3 , SiO 2 , and TiO 2 and lithium-ion conductive fillers such as lithium aluminum germanium phosphate (LAGP), lithium aluminum titanium phosphate (LATP), and lithium lanthanum zirconium oxide (LLZO), which are dispersed in polymer matrices. A Lewis acid–base interaction takes place between the polar groups of the polymer to improve the amorphous nature of the polymer chains and enhance the thermal stability, mechanical strength, and electrochemical properties of the nanocomposite polymer membrane. − Among all ceramic fillers, the NASICON-structured LATP ceramic gains significant attention owing to its chemical stability at room temperature, high lithium-ion conductivity, easy preparation, and low cost. ,− Various synthesis routes like tape casting, plasticizer extraction, solution casting, phase inversion, hot press, drop casting, and electrospinning were used for developing the composite polymer electrolyte membranes. − The electrospinning method was considered an evolved method for developing a three-dimensional (3D) nanofibrous membrane with an interconnected pore structure, which enhances the lithium-ion pathway in the composite polymer electrolyte.…”
