A 3D highly conductive urchin-like NiCo2S4 nanostructure has been successfully prepared using a facile precursor transformation method. Remarkably, the electroactive material demonstrates superior electrochemical performance with ultrahigh high-rate capacitance, very high specific and excellent cycling stability.
NiCo2S4 porous nanotubes are synthesised by a sacrificial template method based on the Kirkendall effect. The as-prepared nanotube electrode shows specific capacitance of 1093 F g−1 at current density 0.2 A (933 1 g−1).
Abstract In recent years, rechargeable aqueous zinc‐ion batteries (ZIBs) have received much attention. However, the disproportionation effect of Mn 2+ seriously affects capacity retention ZIBs during cycling. Here, 3 O 4 cathode is improved by effective valence engineering. The engineering caused bulk oxygen defects, which are in situ derived from Mn‐metal organic framework carbonization. Bulk defects can change (MnO 6 ) octahedral structure, improves structural stability and inhibits...

Abstract Water corrosion and dendrite growth seriously break the zinc plating/stripping process at electrolyte/anode interface, causing instability of metal anode aqueous batteries. Herein, a self‐consistent hydrophobic interface orderly channels are assembled by three quaternary ammonium cationic surfactants, which can block water erosion. Of particular interest, experimental results combined with theoretical calculation (DFT) reveals that groups in cations determinaning factor kinetic ion...
Abstract Zinc metal batteries show tremendous applications in wide‐scale storages still impeded by aqueous electrolytes corrosion and interfacial water splitting reaction. Herein, a zincophobic electrolyte containing succinonitrile (SN) additive is proposed, the SN shows lower affinity for zinc but stronger solid‐state interphase (SEI). In electrolyte, hydroxide sulfate (ZHS) more inclined to accumulate horizontally, forming dense SEI protective layer on surface of Zn anode, effectively...
Abstract Photodetectors (PDs) based on perovskite nanowires are among the most promising next‐generation photodetection technologies; however, their poor long‐term stability is biggest challenge limiting commercial application. Herein, an ionic liquid, 1‐butyl‐3‐methylimidazolium tetrafluoroborate (BMIMBF 4 ), incorporated as additive into methylammonium lead triiodide (MAPbI 3 ) nanowires; this not only effectively passivates defects to inhibit degradation but also leads formation of...
Stable zinc (Zn)/electrolyte interface is critical for developing rechargeable aqueous Zn-metal batteries with long-term stability, which requires the dense and stable Zn electrodeposition.
