Zinc (Zn) holds great promise as a desirable anode material for next-generation rechargeable batteries. However, the uncontrollable dendrite growth and low coulombic efficiency of Zn plating/stripping process severely impede further practical applications Zn-based Here, these roadblocks are removed by using in situ grown zeolitic imidazolate framework-8 (ZIF-8) ion modulation layer to tune diffusion behavior Zn2+ ions on anodes. The well-ordered nanochannels N species ZIF-8 can effectively...

The main limitation urea‐based cells their relatively low power densities due the sluggish anode reactions. Rapid advances in nanocatalysts used urea electro‐oxidation have been achieved lowering overpotential improving activity. Urine, as natural resource urea, also an environmental pollutant. Most technologies treating urine with...
Nickel is an ideal non-noble metal anode catalyst for direct urea fuel cell (DUFC) due to its high activity. However, there exists a large overpotential toward electrooxidation.

Abstract Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention as a next‐generation energy storage system because of their inherent safety, high capacity, and cost effectiveness. However, the poor cycling durability low coulombic efficiency zinc anodes substantially restrict further development, which should be attributed to severe dendrite growth, shape change, surface passivation, self‐corrosion, byproduct formation across repeated plating/stripping processes. To address...
