摘      要：The full utilization of active metal sites is meaningful for enhancing the application of materials in the energy storage field. In this study, a nickel-based nanosphere（NiSA-SSA-Co） precursor was obtained via effective doping based on a dual-ligand complex. With thermal activation, the pore microstructure of the precursor was modulated, and a transition state complex（NiSASSA-Co-350） was fabricated. NiSA-SSA-Co-350 not only retains part of the framework structure, but also fully exposes the metal nodes and enhances the efficiency of the active sites. NiSA-SSA-Co-350 exhibits optimal conductivity and intrinsic reactivity when applied as an electrode material for nickel-zinc batteries（NZBs）. In contrast to the precursor, NiSA-SSA-Co-350with large specific surface area shows a higher specific capacity(0.30 mAh cm-2at 3 mA cm-2). This work hopefully provides a new perspective on the study of nanomaterial porosity in energy storage applications.
