Abstract
Abstract The introduction of the redox couple of triiodide/iodide (I 3 − /I − ) into aqueous rechargeable zinc batteries is a promising energy‐storage resource owing to its safety and cost‐effectiveness. Nevertheless, the limited lifespan of zinc–iodine (Zn–I 2 ) batteries is currently far from satisfactory owing to the uncontrolled shuttling of triiodide and unfavorable side‐reactions on the Zn anode. Herein, space‐resolution Raman and micro‐IR spectroscopies reveal that the Zn anode suffers from corrosion induced by both water and iodine species. Then, a metal–organic framework (MOF) is exploited as an ionic sieve membrane to simultaneously resolve these problems for Zn–I 2 batteries. The multifunctional MOF…
