Combined experimental and computational studies show that, upon reducing the diameter of Pt nanoparticles down to 1 nm, a collapse in crystalline structure occurs spontaneously thus-induced quantum size effect causes decline catalytic activity toward hydrogen oxidation reaction (HOR). The conversion from amorphous is rationalized by molecular dynamic simulations; special electronic revealed via density functional calculations. Not only has present work estimated utilization limit for HOR,...
Nickel–iron sulfides with a sea urchin-like architecture are controllably synthesized and exhibit enhanced OER activities.
Abstract A vertically aligned carbon nanofiber (VACNF) array with unique conically stacked graphitic structure directly grown on a planar Cu current collector (denoted as VACNF/Cu) is used high‐porosity 3D host to overcome the commonly encountered issues of Li metal anodes. The excellent electrical conductivity and highly active lithiophilic edge sites facilitate homogenous coaxial plating/stripping around each VACNF forming uniform solid electrolyte interphase. high specific surface area...

A novel protocol to generate and control porosity in polymeric structures is presented for fabrication of single ion polymer electrolyte (SIPE) membranes lithium batteries. series SIPEs with varying ratios aliphatic aromatic segments was successfully synthesized subsequently blended PVDF-HFP fabricate various sizes pores. The were characterized using techniques including SEM, solvent uptake capacity measurement ionic conductivity. We demonstrate that appropriate membrane enhances...
We report a method to significantly enhance the conductivity of lithium ions in polymeric salt membrane by introducing functionalized meso/macro-pores accommodate mixture organic solvents polymer matrix.

Concentration polarization issues and lithium dendrite formation, which associate inherently with the commercial dual-ion electrolytes, restrict performance of ion batteries. Single conducting polymer electrolytes (SIPEs) high transference numbers (t + ≈ 1) are being intensively studied to circumvent these issues. Herein, poly(ethylene-co-vinyl alcohol) (EVOH) is chosen as backbone then grafted 3-chloropropanesulfonyl(trifluoromethanesulfonyl)imide (LiCPSI) via Williamson's reaction,...
A hyperbranched conjugated Schiff base polymer network was synthesized by condensation between 4,4′,4′′-nitrilotribenzaldehyde and <italic>p</italic>-phenylenediamine.
The all-solid-state single ion conducting polymer electrolyte has a bottleneck in ionic conductivity even though it can prevent concentration polarization. Here, lithium 3,3'-(diallylammonio)bis(propane-1-sulfonyl(trifluoromethyl sulfonyl)imide) (LiDAA(PSI)2) with symmetrical "one positive, two negative" structure and unsaturated double bonds for propagation, is synthesized. LiDAA(PSI)2 copolymerized 1,2-ethanedithiol poly(ethylene glycol) diacrylate via photoinitiated thiol-ene click...

Abstract Lithium-sulfur batteries are highly promising for electric energy storage with high density, abundant resources and low cost. However, the battery technologies have often suffered from a short cycle life poor rate stability arising well-known “polysulfide shuttle” effect. Here, we report novel cell design by sandwiching sp 3 boron based single ion conducting polymer electrolyte film between two carbon films to fabricate composite separator lithium-sulfur batteries. The dense...
