Lithium fluoride (LiF) at the solid electrolyte interface (SEI) contributes to stable operation of polymer-based solid-state lithium metal batteries. Currently, most methods for constructing SEI are based on design polar groups fillers. However, mechanism behind how steric hindrance fillers impacts LiF formation remains unclear. This study synthesizes three kinds porous polyacetal amides (PAN-X, X=NH2 , NH-CH3 N-(CH3 )2 ) with varying hindrances by regulating number methyl substitutions...
Abstract The solid‐state electrolyte interface (SEI) between the polymer and lithium metal anode dramatically affects overall battery performance. Increasing content of fluoride (LiF) in SEI can help uniform deposition inhibit growth dendrites, thus improving cycle stability performance batteries. Currently, most methods constructing LiF involve decomposing salt by polar groups filler. However, there is a lack research reports on how to affect layer Li‐ion batteries increasing charge...

In this work, we report a mild and cost-effective solution method to directly grow Ni-substituted Co3O4 (ternary NiCo2O4) nanorod arrays on Cu substrates. Electrochemical impedance spectroscopy (EIS) measurements show that the values of electrolyte resistance Re charge-transfer Rct NiCo2O4 are 6.8 63.5 Ω, respectively, which significantly lower than those binary (10.4 122.4 Ω). This EIS characterization strongly confirms ternary anode has much higher electrical conductivity electrode...
Silicon nanostructures have been employed as the anodes of lithium-ion batteries to mitigate mechanical and chemical degradation. Conditions for averting fracture identified in terms Si critical size its state charge. Strong dependencies were observed, sizes different shapes found be: ∼90 nm nanoparticles, ∼70 nanowires, ∼33 nanofilms, below which silicon remain undamaged upon lithiation.
Lithium/fluorinated carbon (Li/CFx) primary batteries have essential applications in consumer electronics and medical high-power military devices. However, their application is limited due to the difficulty achieving simultaneous high power density energy CFx cathode. The tradeoff between conductivity fluorine content decisive factor. Herein, by rational design, 3D porous fluorinated graphene microspheres (FGS-x) with both a F/C ratio are successfully synthesized for first time. FGS-x...
POP fillers containing aromatic groups with internal π–π effect can catalyze the decomposition of LiTFSI to form a stable LiF-rich SEI layer and inhibit growth lithium dendrites, which helps cycle PEO-based solid-state batteries.
Exploring high performance cathode materials is essential to realize the adoption of Li-ion batteries for application in electric vehicles and hybrid vehicles. FeF3, as a typical iron-based fluoride, has been attracting considerable interest due both electromotive force value 2.7 V theoretical capacity 237 mA h g−1 (1e− transfer). In this study, we report facile low-temperature solution phase approach synthesis uniform iron fluoride nanocrystals on reduced graphene sheets stably suspended...
O:H–O bond anomalous relaxation and the skin high thermal-diffusivity cool hotter water faster than usual in non-adiabatic ambient system.
Abstract The structural symmetry and molecular separation in water ice remain uncertain. We present herewith a solution to unifying the density, structure order symmetry, size (H-O length d H ) (d OO = L + or O:H of molecules packing terms statistic mean. This reconciles: i) symmetrization O:H-O bond compressed ice, ii) relaxation cooling and, iii) expansion dimer between at surface. With any one , density ρ(g·cm −3 ), as known input, can resolve rest quantities using this that is probing...
Consistency in experimental observations, numerical calculations, and theoretical predictions have revealed that the skins of water ice share same attribute supersolidity characterized by an identical H–O vibration frequency 3450 cm−1. Molecular undercoordination inter-electron-pair repulsion shortens bond lengthens O:H nonbond, leading to a dual process nonbonding electron polarization. This relaxation–polarization enhances dipole moment, elasticity, viscosity, thermal stability these with...
