Innovative synergistic control of electric fields and Zn dynamics for revolutionizing zinc metal battery stability.

Aqueous zinc-ion batteries (ZIBs) are emerging as promising next-generation energy storage systems due to their inherent safety, environmental sustainability, and cost-effectiveness. However, their widespread application is hindered by challenges such as dendritic Zn growth, hydrogen evolution, and corrosion-induced passivation, which compromise performance and scalability. To overcome these obstacles, we developed a novel dual-interface modified zinc anode by integrating a zinc fluoride (ZnF)-silicon (Si) interface using fluorine-doped silicon nanoparticles encapsulated within hollow mesoporous carbon nanospheres (F-Si@HMCS).
