Rechargeable aqueous zinc-ion batteries are promising energy storage devices due to their high safety and low cost. However, they remain in infancy because of the limited choice positive electrodes with capacity satisfactory cycling performance. Furthermore, mechanisms not well established yet. Here we report a highly reversible zinc/sodium vanadate system, where sodium hydrate nanobelts serve as electrode zinc sulfate solution additive is used electrolyte. Different from conventional...
Abstract Aqueous zinc‐ion batteries have been considered as potential energy storage devices owing to their high safety and low cost. Traditional often implement a typical Zn 2+ insertion/extraction mechanism. Compared with traditional mechanism, supercapacitor‐liked dual‐ion mechanism endow the higher operating voltage, better rate capability, longer cycle life. Herein, aqueous Zn/polyaniline are developed, which can combine mechanisms. The deliver excellent electrochemical performance,...
Flexible nanostructured reduced graphene oxide-sulfur (rGO-S) composite films are fabricated by synchronously reducing and assembling GO sheets with S nanoparticles on a metal surface. The architecture in such not only provides effective pathways for electron transport, but also suppresses the diffusion of polysulfides. Furthermore, they can serve as cathodes flexible Li-S batteries.
Aqueous zinc-ion batteries (ZIBs) are considered as a promising energy storage system due to their low cost and high safety merits. However, they suffer from the challenge of uncontrollable dendrite growth non-uniform zinc deposition, which increases internal resistance causes battery failure. Herein, Ag coating fabricated by facile surface chemistry route on metal was developed guide uniform deposition. Ag-coated Zn shows improved electrolyte wettability, small deposition overpotential,...
Abstract Lithium dendrite growth during repeated charge and discharge cycles of lithium‐metal anodes often leads to short‐circuiting by puncturing the porous separator. Here, a morphological design, nano‐shield, for separators resist dendrites is presented. Through both mechanical analysis experiment, it revealed that separator protected nano‐shield can effectively inhibit penetration lithium owing reduced stress intensity generated therefore mitigate short circuit Li metal batteries. More...
By combining the benefits of high entropy (HE) and carbon wrapping (CW), HEPBAs@0.1C achieves excellent electrochemical performance unprecedented stability in ambient environment.
A novel non-aqueous hybrid supercapacitor was fabricated from two spherical materials – an activated mesocarbon microbead (AMCMB) and MnO2 nanowire-sphere, as the negative positive electrodes, respectively. The preliminary results for this energy-storage device, which operates over a wide voltage range (0.0–3.0 V) using 1 M Et4NBF4 in acetonitrile (AN) electrolytes, are presented. On basis of single electrode, AMCMB|MnO2 displays high specific capacitance 228 F g−1 at scan rate 10 mV s−1,...
Ordered mesoporous carbon/iron oxide composites were prepared by cooperative self-assembly of poly(t-butyl acrylate)-block-polyacrylonitrile (PtBA-b-PAN), which contains both a carbon precursor block and porogen block, phenol-functionalized iron nanoparticles (NPs). Because the selective hydrogen bonding between NPs PAN, preferentially dispersed in PAN domain subsequently within framework. nanocomposites with Fe2O3 mass loadings as high 30 wt % obtained upon carbonization at copolymer 700...
Abstract Asymmetric supercapacitors have attracted tremendous attention in energy storage devices since they an enhanced density comparison with symmetric supercapacitor devices. Furthermore, the development of diverse and flexible electronic requires asymmetric to be various configurations. However, it is still a challenge develop universal strategy obtain both capacitive Faradic electrodes architectures. Herein, spontaneously reducing/assembling alkaline condition developed fabricate...
The lithium sulfur (Li-S) battery has attracted much attention due to its high theoretical capacity and energy density. However, cycling stability rate performance urgently need improve because of shuttle effect. Herein, oxygen-doped carbon on the surface reduced graphene oxide (labeled as ODC/rGO) was fabricated modify separators Li-S batteries limit dissolution polysulfides. mesoporous structure in ODC/rGO can not only serve physical trapper, but also provide abundant channels for fast ion...
Recent development in flexible electronics has promoted the increasing demand for their energy storage systems that will be lightweight, thin, flexible, and even foldable. Although various supercapacitors recently have been successfully developed, design assembly of highly foldable received less attention. Furthermore, are general operated independently with other electronics, resulting some space consumption from external connection system. Therefore, authors fabricate all-solid-state...
