Ultrahigh Energy and Power Density in Ni–Zn Aqueous Battery via Superoxide-Activated Three-Electron Transfer

Highlights

Efficient activation of Ni electrode employs chronopotentiostatic superoxidation.
Novel superoxide activation mechanism realizes the redox reaction with three-electron transfer (Ni ↔ Ni³⁺).
As-prepared CPS-Ni||Zn batteries exhibit simultaneously ultrahigh energy and power densities.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
