A systematic investigation established a significant correlation between the 2D to G band intensity ratio ( I / ) in Raman spectrum and internal kinetic barrier for sodium-ion transfer, achieving highest sodium plateau capacity of ∼400 mA h g −1 (A30 sample).
We introduce silk textile-based water-splitting electrodes that can significantly increase the electrocatalytic performance for both HER and OER by a carbonization/interfacial assembly-driven electroplating approach.
Abstract Bifunctional hybrid anodes (BHAs), which are both a high‐performance active host material for lithium‐ion storage as well guiding agent homogeneous lithium metal nucleation and growth, exhibit significant potential next‐generation high‐energy‐density batteries (LIBs). In this study, sulfur‐doped hard carbon nanosphere assemblies (S‐HCNAs) were prepared through hydrothermal treatment of liquid organic precursor, followed by high‐temperature thermal annealing with elemental sulfur...
3D-structured bifunctional MXene paper electrode (3D-BMPE), which has distinctive material properties, was fabricated to protect Al deposition/dissolution reactions with improved redox kinetics.
A distinctive solid-solution potassium-ion intercalation behavior of disordered graphitic carbon materials was observed.
Thin pyroprotein coating layers containing numerous oxygen and nitrogen heteroatoms were introduced on the surface of CFs (P-CFs), their catalytic effects redox reaction V<sup>2+</sup>/V<sup>3+</sup> couples for VRFBs investigated.
Abstract Zinc metal anodes (ZMA) have high theoretical capacities (820 mAh g −1 and 5855 cm −3 ) redox potential (−0.76 V vs. standard hydrogen electrode), similar to the electrochemical voltage window of evolution reaction (HER) in a mild acidic electrolyte system, facilitating aqueous zinc batteries competitive next‐generation energy storage devices. However, HER byproduct formation effectuated by water‐splitting deteriorate performance ZMA, limiting their application. In this study, key...
Multiwalled carbon nanotubes (MWCNTs) were embedded in electrospun bacterial cellulose (BC) nanofibers, which prepared using an electrospinning method. In this study, Gluconacetobacter xylinum BRC5 was employed to produce a hydrogel-like sheet. BC difficult process the solution stat because of large concentration intra- or inter-molecular hydrogen bonds. ionic liquid, 1-allyl-3-methyl-imidazolium chloride, used dissolve BC. To form 5 wt% solutions both with and without MWCNTs electrospun....
Abstract A simple method was used to synthesize the hybrid nanocomposites consisting of functionalized multiwalled carbon nanotube composites (MWCNTs) with polyaniline incorporated silver nanoparticles (a-MWCNT/PANI-Ag) through an emulsion polymerization at room temperature in order enhance electrical conductivity polyaniline. The composite Ag 5% higher than same weight percent for without nanoparticles, and thermal stability dramatically increased from 54% (a-MWCNT/PANI) 69% incorporation...
Abstract Studies on three‐dimensional structured carbon templates have focused how to guide homogeneous lithium metal nucleation and growth for anodes (LMAs). However, there is still insufficient evidence a key factor achieve their high electrochemical performance. Here, the effects of nanopores sulfur doping carbon‐based nanoporous host (CNH) electrode materials LMAs were investigated using natural polymer‐derived CNHs. Homogeneous pore‐filling behaviors in CNH first observed by ex situ...
Diamond metal-insulator-semiconductor diodes and field-effect transistors (MISFETs) have been prepared using CaF2 gate insulator nondoped (in some cases, boron was doped) diamond homoepitaxial films. The resultant capacitance-voltage (C-V) curves drain current-drain voltage (ID−VD) strongly depended on the amount of oxygen contamination surface. From analyses C-V ID−VD curves, it found that induced surface states with two distribution peaks locating very near valence band edge at energy ∼1...
