Constructing stable surface modification layer is an effective strategy to suppress dendrite growth and side reactions of Zinc (Zn) metal anode in aqueous Zn-ion battery. Herein, a multicomponent Cu-Zn alloy interlayer with superior Zn affinity, high toughness inhibition effect on lattice distortion constructed foil (Cu-Zn@Zn) fabricate ultra-stable anode. Owning the advantages binding energy atoms less contact area between metallic electrolyte, as-prepared Cu-Zn@Zn electrode not only...
Poly(vinylidene fluoride) (PVDF)-based solid electrolytes with a Li salt-polymer-little residual solvent configuration are promising candidates for solid-state batteries. Herein, we clarify the microstructure of PVDF-based composite electrolyte at atomic level and demonstrate that Li+-interaction environment determines both interfacial stability ion-transport capability. The polymer works as "solid diluent" filler realizes uniform distribution. We propose universal strategy constructing...
The coupling of high-capacity cathodes and lithium metal anodes promises to be the next generation high-energy-density batteries. However, fast-structural degradations cathode anode challenge their practical application. Herein, we synthesize an electrolyte additive, tris(2,2,3,3,3-pentafluoropropyl) borane (TPFPB), for ultra-stable (Li) metal||Ni-rich layered oxide It can preferentially adsorbed on surface form a stable (B F)-rich interface film, which greatly suppresses electrolyte-cathode...
Most of the catalysts in lithium sulfur (Li-S) batteries present low electronic conductivity and polysulfides (LiPSs) must diffuse onto surface carbon materials to achieve their conversion reaction. It is a significant challenge instantaneous transformation LiPSs Li2 S Li-S suppress shuttle effect LiPSs. Herein, unique electron ion co-conductive catalyst carbon-coated Li1.4 Al0.4 Ti1.6 (PO4 )3 (C@LATP) developed, which not only possesses strong adsorption LiPSs, but, more importantly, also...
Abstract Constructing stable surface modification layer is an effective strategy to suppress dendrite growth and side reactions of Zinc (Zn) metal anode in aqueous Zn‐ion battery. Herein, a multicomponent Cu−Zn alloy interlayer with superior Zn affinity, high toughness inhibition effect on lattice distortion constructed foil (Cu−Zn@Zn) fabricate ultra‐stable anode. Owning the advantages binding energy atoms less contact area between metallic electrolyte, as‐prepared Cu−Zn@Zn electrode not...
Abstract Zirconium compounds has been widely attention over the last decades due to its excellent physical and chemical properties. nitride nanopowders were synthesized via a simple direct carbothermic nitridation process of internal gel derived zirconia in presence nano-sized carbon black. The effects reaction temperature, dwell time molar ratio black Zr (C/Zr) on phase composition, grain size crystal parameters products studied. Based upon analysis crystallite evolution microstructure...
The composite solid-state electrolytes (CSEs) are one of the most promising for advanced Li metal batteries. However, it is unclear effect induced electric field inside CSEs on Li-ion transport. Herein, we design a compact CSE by imbedding lithium niobate (LiNbO3) with both high ionic conductivity and dielectric constant into poly(vinylidene fluoride) matrix (NPC). LiNbO3 significantly enhances internal NPC along particles establishes uniform interfacial between electrodes, which...
A metastable NaCl-structure Cr carbide was formed by 50 keV carbon-ion implantation into pure chromium metal films. The structure of the phase identified selected-area electron diffraction to be face-centred cubic (FCC) with a lattice constant 0.403 nm. stable only up temperature about 250 degrees C and destabilized at higher temperature, probably because oxidation. formation also confirmed Auger spectroscopy measurements. heat calculated less negative than those for Ti V carbides, i.e. -7...
Abstract A series of Ba 1- x La F 2+ composition powders with different values were prepared by water and ethanol mixed solvent method. The effects on the phase composition, crystal structure electrochemical properties electrolyte studied. electrical conductivity at temperatures was investigated impedance spectroscopy. results transmission electron microscopy showed that ranged in size from 10 to 25nm dominated crystalline phases. XRD show gradually changes fluorite tysonite increase value....
Abstract Nanocrystalline zirconium nitride (ZrN) powder was prepared by using internal gelation combined with carbothermic nitridation. As a carbon source, fructose added in the process to facilitate homogeneous dispersion. Fructose decomposed and ultrafine generated in-situ at high temperature. The acted as reducing agent remove oxygen atoms nitridation process. effects of on phase composition, morphology, grain size specific surface area were analysed. led peculiar morphology particles....
