A rechargeable zinc ion capacitor (ZIC) employing a metallic anode, nature-abundant materials-derived high-performance cathode, and an aqueous electrolyte represents interesting combination of high capacitance, power, safety operation, overall sustainable economic system, which make them leading power source to portable consumer electronics. However, it is often challenge fabricate large-area flexible device with anode due the characteristic rigidity metal. Herein we present ZIC based on...
Orthorhombic crystal structure of the V3O7·H2O material has large interlayer spacing with an open tunnel, making it promising as intercalation-based cathode for aqueous zinc-ion batteries. However, structural degradation and dissolution cause quick capacity fading V3O7·H2O. We addressed this issue via a dual modification by pre-intercalation Ag(I) inside layers (henceforth will be mentioned AgxV3O7·H2O) simultaneous in situ composite formation reduced graphene oxide (rGO). Computationally,...
Herein we demonstrate the fabrication of a high-performance rechargeable zinc ion battery based on laser-scribed carbon (LSC)-supported electrodeposited anode and vanadium oxide (V5O12·6H2O) cathode with planar-interdigitated electrode architecture polymeric solid electrolyte. This is first report full-cell Zn//V5O12·6H2O planar flexible where practical loading (∼76 times that loading) maintained. The Zn@LSC showed excellent stability very low polarization over tested 500 h (750 cycles). We...
Vanadium oxyhydroxide has been recently investigated as a starting material to synthesize different phases of vanadium oxides by electrochemical or thermal conversion and used an aqueous zinc-ion battery (AZIB) cathode. However, the low-valent have poor phase stability under ambient conditions. So far, there is no study on understanding evolution such their effect performance toward hosting Zn2+ ions. The primary goal work develop high-performance AZIB cathode, highlight current insight into...
A zinc-ion battery (ZIB) employing an aqueous electrolyte, that is, (AZIB), represents a unique combination of high energy and power with much-desired safety. In this respect, vanadium oxide-based cathodes, open frameworks rich valence states, have shown promising characteristics toward hosting the Zn2+ ions. Nevertheless, degradation host during continuous (de-)intercalation structural dissolution in electrolyte affects capacity cycle life. Herein, we represent long life AZIB based on...
Developing high-performance, safer, and affordable flexible batteries is of urgent need to power the fast-growing electronics market.

Abstract Electrochemical hydrogen generation via water splitting is the greenest approach toward economy. To satisfy practical utilization, electrocatalyst for evolution reaction (HER) must be of low cost with high catalytic activity. Accordingly, transition metal based electrocatalysts have attracted significant research interest. Herein, this work demonstrates an efficient HER on copper nickel sulfide (CNS), and Agaricus bisporus biomass derived functionalized carbon (FMCs) nanocomposites,...
