Interfacial electronic nanoarchitectonics is employed to regulate iodine chemistry in aqueous Zn–I2 batteries by constructing a TiN-decorated biomass-derived carbon heterostructure. The tailored TiN–PNC interface induces charge redistribution and orbital coupling, enhancing iodine adsorption, accelerating redox kinetics, and suppressing polyiodide shuttling, thereby enabling ultralong cycling stability and practical pouch-cell performance.
