Article Synopsis
- Rechargeable nickel-zinc (Ni-Zn) batteries are promising for large-scale use due to their high voltage, cost-effective zinc anode, and good safety, but suffer from cathode material limitations like overcharging and capacity loss.
- A new synthesis method for hierarchical nickel-cobalt (Ni-Co) hydroxides is introduced, utilizing metal-organic frameworks (MOFs) to create hollow structures that boost surface area and improve conductivity.
- With the optimized Ni-Co hydroxide, the Ni-Zn battery shows impressive energy outputs of 338 Wh kg-1 at a lower power and 142 Wh kg-1 at high power, demonstrating the potential of the MOF approach for better battery performance.
Constructing well-defined nanostructures consisting of the multiple components with distinctive features are a promising but challenging strategy to develop advanced electroactive materials for energy storage applications. Herein, heterogeneous Ni-Co phosphide/phosphate with a specific hollow sea-urchin-like structure has been synthesized as advanced electroactive materials for both hybrid supercapacitor (HSC) and alkaline zinc-metal battery (AZB) applications. The heterogeneous Ni-Co phosphide/phosphate combines the merits of improved electrolyte interfacial property from the specific hollow sea-urchin-like structure, high electron-conductivity of phosphide, and better ion adsorption and solid diffusion property of phosphate.
