This invention discloses a zinc anode, its preparation method, and a battery, belonging to the field of electrochemical technology. It solves the problem of reduced coulombic efficiency and reduced cycle life in existing batteries using zinc-based metal anodes. A zinc anode includes a zinc substrate and a composite modification layer coated on the surface of the zinc substrate; the composite modification layer is formed by combining polystyrene microspheres and an ionic liquid, and the thickness of the composite modification layer is 5-30 μm. The composite modification layer on the zinc anode of this invention does not significantly hinder Zn²⁺ deposition. + The transmission of electrons can maintain the electron conversion reaction in the strong acid electrolyte, enabling the battery system to achieve excellent cycle stability while maintaining high voltage output. The acidic aqueous zinc-manganese full cell constructed with zinc anode prepared using this composite modification layer still maintains stable rate performance at high current density.
