Metal–organic frameworks (MOFs) have been considered as a class of promising electrode materials for supercapacitors owing to their large surface area, rich porosity, and variable redox sites; however, direct application pristine MOFs in energy storage has largely hindered by poor electrical conductivity stability issues. In this work, we demonstrate facile two-step approach address the controlled growth Ni-MOF arrays on NiCo2O4 nanowires modulating formation reaction MOFs. By taking...
Abstract Engineering the structure and chemistry of solid electrolyte interface (SEI) on electrode materials is crucial for rechargeable batteries. Using hard carbon (HC) as a platform material, correlation between Na + storage performance, properties SEI comprehensively explored. It found that “good” layer HC may not be directly associated with certain kinds components, such NaF 2 O. Whereas, arranging nano components refined structures constructs foundation enables fast stability in Na‐ion...
The air-sensitivity of transition metal oxide cathode materials (NaxTMO2, TM: metal) is a challenge for their practical application in sodium-ion batteries large-scale energy storage. However, the deterioration mechanism NaxTMO2 under ambient air unclear, which hinders precise design air-stable NaxTMO2. Here, we revealed origin degradation by capturing initial status and microstructural evolution atmospheres with optimal humidity. It was found that insertion CO2 into Na layers along (003)...
A template-free and surfactant-free method for the synthesis of highly monodisperse phenol formaldehyde resin corresponding carbon nano/microspheres with excellent size tunability has been developed first time after investigating a series derivatives, including 3-methylphenol, 1,3,5-trihydroxybenzene, 2-aminophenol, 3-aminophenol, 4-aminophenol. The is based on polymerization reaction 3-aminophenol in mixture solutions water ethanol to generate 3-aminophenol/formaldehyde (APF) colloidal...
The development of flexible energy storage devices for portable and wearable electronics has aroused increasing interest. In this work, three-dimensional hierarchical NiCo2O4@NiMn-LDH nanowire/nanosheet arrays have been successfully fabricated on carbon cloth through a facile hydrothermal calcination synthetic method. Benefiting from the sophisticated hybrid nanoarchitectures with desirable structure components, optimized electrode is found to deliver remarkable specific capacity 278 mA h...
To obtain high-performance hybrid supercapacitors (HSCs), a new class of battery-type electrode materials with hierarchical core/shell structure, high conductivity and rich porosity are needed. Herein, we propose facile one-step sulfuration approach to achieve the fabrication NiCo2S4@NiCo2S4 nanotube/nanosheet arrays (NTSAs) on carbon cloth, by taking hydrothermally grown Ni-Co precursor@Ni-Co precursor nanowire/nanosheet (NWSAs) as starting templates. The optimized NTSAs demonstrates an...
Hierarchical NiCo<sub>2</sub>S<sub>4</sub>@NiMoO<sub>4</sub> nanotube/nanosheet arrays were successfully fabricated on Ni foam as battery-type electrodes for high-performance hybrid supercapacitors.
The apparent cathodic current on the Ti surface in acidic solution is composed of three reactions: reductions oxide film, H+, and O2. However, classical electrochemical tests usually provide coupled multi-reaction currents. Furthermore, dissolved oxygen makes situ measurements significant due to thermodynamic instability Ti. In this study, effects pre-reduction hydrogen evolution reaction (HER) kinetics were investigated by composition characterizations. HER was quantitatively separated from...
The galvanic corrosion of titanium/304 stainless steel (TA1/304SS) couple was investigated in neutral and acidic solution with without fluorine ion (F-) using macro-electrochemical technique scanning electrochemical microscope (SECM). results show that the synergistic effect H+ F- affects passive film on surface couple, resulting a great change heterogeneous reaction rate constant activity characterized by approach curve mapping SECM feedback mode. In addition, typical polarity reversal...
