Yet, conventional ion\u2010intercalation systems suffer from structural degradation, while reversible metal electrodeposition systems are limited by dendrite growth and poor durability. Here, we report a Zn\u2010coupled electrochemical device, enabled by coordination\u2010governed reversible polyiodide deposition. By introducing a highly symmetric tetramethylammonium cation ([N\n                    <jats:sub>1111<\/jats:sub>\n                    ]\n                    <jats:sup>+<\/jats:sup>\n                    ), precise spatial matching with linear I\n                    <jats:sub>5<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    is achieved, inducing the formation of a highly stable solid\u2010state [N\n                    <jats:sub>1111<\/jats:sub>\n                    ]\n                    <jats:sup>+<\/jats:sup>\n                    I\n                    <jats:sub>5<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    complex. This effectively suppresses the shuttle effect of polyiodides and enables highly reversible I\n                    <jats:sup>\u2212<\/jats:sup>\n                    \/I\n                    <jats:sub>5<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    conversion. Meanwhile, [N\n                    <jats:sub>1111<\/jats:sub>\n                    ]\n                    <jats:sup>+<\/jats:sup>\n                    further regulates the solvation structure at the Zn electrode via interfacial adsorption, constructing a water\u2010deficient inner Helmholtz layer that promotes uniform Zn\n                    <jats:sup>2+<\/jats:sup>\n                    deposition. Benefiting from the synergistic stabilization of the solid\u2010state polyiodide deposition\/dissolution and reversible Zn plating\/stripping process, the assembled device delivers a high optical contrast of 75.5% at 650\u00a0nm, fast switching speeds (3.9\/6.5 s), and 84.9% retention after 20\u00a0000 cycles. The device blocks 93.6% of solar irradiation in the colored state, enabling a 4\u00b0C\u201310\u00b0C cooling effect and 16.4% annual energy savings. This work establishes a new design paradigm for Zn\u2010coupled electrochromic devices based on confined solid\u2010state polyiodide chemistry, providing a promising strategy for constructing durable and scalable smart windows.\n
