Abstract Sodium metal batteries have potentially high energy densities, but severe sodium-dendrite growth and side reactions prevent their practical applications, especially at temperatures. Herein, we design an inorganic ionic conductor/gel polymer electrolyte composite, where uniformly cross-linked beta alumina nanowires are compactly coated by a poly(vinylidene fluoride-co-hexafluoropropylene)-based gel through strong molecular interactions. These combined with the layer create dense...
Sodium-ion batteries are promising alternatives to lithium-ion for large-scale applications. However, the low capacity and poor rate capability of existing anodes sodium-ion bottlenecks future developments. Here, we report a high performance nanostructured anode material that is fabricated by energy ball milling form black phosphorus/Ketjenblack–multiwalled carbon nanotubes (BPC) composite. With this strategy, BPC composite with phosphorus content (70 wt %) could deliver very initial...
High-performance lithium-ion batteries are commonly built with heterogeneous composite electrodes that combine multiple active components for serving various electrochemical and structural functions. Engineering these toward drastically improved battery performance is hinged on a fundamental understanding of the mechanisms their synergy or trade-off effects. Herein, we report rational design, fabrication, yolk@shell Bi2S3@N-doped mesoporous carbon (C) anode, consisting Bi2S3 nanowire (NW)...
Severe interfacial side reactions of polymer electrolyte with LiNi0.8 Co0.1 Mn0.1 O2 (NCM811) cathode and Li metal anode restrict the cycling performance solid-state NCM811/Li batteries. Herein, we propose a chemically stable ceramic-polymer-anchored solvent composite high ionic conductivity 6.0×10-4 S cm-1 , which enables batteries to cycle 1500 times. The Li1.4 Al0.4 Ti1.6 (PO4 )3 nanowires (LNs) can tightly anchor essential N, N-dimethylformamide (DMF) in poly(vinylidene fluoride) (PVDF),...
P2-type sodium nickel manganese oxide-based cathode materials with higher energy densities are prime candidates for applications in rechargeable ion batteries. A systematic study combining situ high X-ray diffraction (HEXRD), ex absorption fine spectroscopy (XAFS), transmission electron microscopy (TEM), and solid-state nuclear magnetic resonance (SS-NMR) techniques was carried out to gain a deep insight into the structural evolution of P2–Na0.66Ni0.33–xZnxMn0.67O2 (x = 0, 0.07) during...
Abstract The electrochemo‐mechanical effects on the structural integrity of electrode materials during cycling is a non‐negligible factor that affects cyclability and rate performance all solid‐state batteries (ASSBs). Herein, combined with in situ electrochemical impedance spectroscopy (EIS), focused ion beam (FIB)–scanning electron microscope (SEM), solid state nuclear magnetic resonance (ssNMR) techniques, behavior are compared conventional polycrystalline NCM811 (LiNi 0.8 Co 0.1 Mn O 2...
Advanced spectroscopy methods quantitatively elucidate the failure process of lithium metal batteries.
The crucial role of Li-ion transport efficiency in cathodes is revealed for the room temperature performance all-solid-state lithium batteries and a highly efficient “solid–polymer–solid” elastic ion network constructed cathode.
Poor ion and high electron transport at the grain boundaries (GBs) of ceramic electrolytes are primary reasons for lithium filament infiltration short-circuiting all-solid-state metal batteries (ASLMBs). Herein, it is discovered that Li2 CO3 GBs Li7 La3 Zr2 O12 (LLZO) sheets reduced to highly electron-conductive LiCx during cycling, resulting in penetration LLZO. The ionic electronic conductivity within LLZO can be simultaneously tuned using sintered Li3 AlF6 . generated LiAlO2 (LAO)...
High-power phosphor-converted white light-emitting diodes (hp-WLEDs) have been widely involved in modern society as outdoor lighting sources. In these devices, due to the Joule effect, high applied currents cause operation temperatures (>500 K). Under conditions, most phosphors lose their emission, an effect known thermal quenching (TQ). Here, we introduce a zero-dimensional (0D) metal halide, Rb3InCl6:xSb3+, suitable anti-TQ phosphor offering robust behavior up 500 K. We ascribe this of...
Na3V2(PO4)2F3 is a novel electrode material that can be used in both Li ion and Na batteries (LIBs NIBs). The long- short-range structural changes ionic electronic mobility of as positive NIB have been investigated with electrochemical analysis, X-ray diffraction (XRD), high-resolution 23Na 31P solid-state nuclear magnetic resonance (NMR). NMR spectra XRD refinements show the ions are removed nonselectively from two distinct sites, fully occupied Na1 site partially Na2 site, at least...
When aprotic Li-O2 batteries discharge, the product phase formed in cathode often contains two different morphologies, that is, crystalline and amorphous Li2 O2 . The morphology of impacts strongly on electrochemical performance cells terms energy efficiency rate capability. Crystalline is readily available its properties have been studied depth for batteries. However, little known about because rarity high purity. Herein, has synthesized by a rapid reaction tetramethylammonium superoxide...
An organic cathode material, poly(2,5-dihydroxyl-1,4-benzoquinonyl sulfide) (PDBS), has been synthesized and assessed as a material for lithium ion batteries. The prepared polymer is characterized by 13C solid state NMR, FTIR, XPS elemental analysis techniques. FTIR results indicate that the chlorine of chloranilic acid (CLA) successfully substituted sulfur after sulfurization reaction. Elemental shows mainly composed dimer trimer. electrochemical measurements show initial discharge capacity...
Silicon-based anodes have the potential to be used in next-generation lithium ion batteries owing their higher storage capacity. However, large volume change during charge/discharge process and repeated formation of a new solid electrolyte interface (SEI) on re-exposed Si surface should overcome achieve better electrochemical performance. Fluoroethylene carbonate (FEC) has been widely as an additive for Si-based anodes, but intrinsical mechanism performance improvement is not clear yet....
