Unlocking Durable and Sustainable Zinc–Iodine Batteries via Molecularly Engineered Polyiodide Reservoirs

in the cathode). Importantly, the cage's solubility-driven regeneration capability retains 85.4% initial capacity over three reuse cycles. This work establishes covalent organic superphanes as a transformative platform for long-life ZIBs, offering a dual solution to shuttle suppression and electrode sustainability through structural confinement and dynamic recyclability.
