Among various candidates, zinc\u2010iodine (Zn\/\/I\n                    <jats:sub>2<\/jats:sub>\n                    ) microbatteries (MBs) are attractive owing to their intrinsic safety, low cost, and rapid iodine redox chemistry. Herein, a printed coplanar Zn\/\/I\n                    <jats:sub>2<\/jats:sub>\n                    MB is developed using a cathode\u2010confined iodine strategy, in which redox\u2010active iodine is immobilized within a rationally engineered polyaniline (PANI) and activated\u2010carbon (AC) (I\n                    <jats:sub>2<\/jats:sub>\n                    @AC\u2010PANI) composite cathode framework. The synergistic AC\u2010PANI architecture enhances iodine utilization, charge\u2010transfer kinetics, and electrochemical reversibility, resulting in improved capacity, rate capability, and cycling stability. Through a combination of ex situ spectroscopic analyses, electrochemical measurements, self\u2010discharge studies, and density functional theory (DFT) calculations, stronger interactions between iodine species and the AC\u2010PANI framework are identified, together with enhanced charge\u2010transfer characteristics compared with AC alone. As a result, the coplanar Zn\/\/I\n                    <jats:sub>2<\/jats:sub>\n                    microbattery delivers an areal energy of 36.35\u00a0\u00b5Wh\u00a0cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    at an areal power of 50\u00a0\u00b5W\u00a0cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    and retains 86.4% of its initial capacity after 2000 cycles. This work demonstrates that cathode\u2010confined halogen chemistry combined with AC\u2010PANI engineering provides an effective strategy for developing high\u2010performance coplanar microbatteries and offers a promising route toward safe, integrable, and durable microscale energy\u2010storage systems.\n
