Flowing zinc slurry for long-duration energy storage (opens in new tab)

Long-duration energy storage is critical for integrating renewable energy, yet few technologies simultaneously achieve low cost, long cycle life and high safety. Here we report a flowing Zn slurry (FZS) battery in which nanoscale Zn particles dispersed within a conductive network undergo reversible Zn/Zn2+ redox conversion with enhanced stability. Ligand-assisted confinement coordinates onto Zn nanoparticle surfaces, suppressing excessive Zn growth and parasitic reactions, enabling uniform, m...
