Angstrom‐Scale Confined Ion Sieve and Accelerator for Efficient Aqueous Zinc Batteries (Adv. Mater. 53/2026)

Angstrom-Scale Confined Ion Sieve and Accelerator The cover illustrates an angstrom-scale ion sieve and accelerator formed by stacked Ti0.87O2 nanosheets. Atomic Ti vacancies and confined interlayer free spacing create dual transport pathways that selectively accelerate desolvated Zn2+ while excluding H2O and SO42−. This precisely regulated Zn2+ flux suppresses parasitic reactions and dendrite growth, enabling highly reversible aqueous zinc-metal batteries. More details can be found in the Research Article by Pan Xiong, Guoxiu Wang, Junwu Zhu, and co-workers (DOI: 10.1002/adma.74289).
