▎ 摘  要

NOVELTY - Aqueous zinc iodine secondary battery anode material comprises 5-15 wt.% binder, 5-30 wt.% conductive agent and 55-90 wt.% anode active material. USE - Aqueous zinc iodine secondary battery anode material used for aqueous zinc-iodine secondary battery. ADVANTAGE - The aqueous zinc iodine secondary battery anode material has excellent performance in terms of multiplying power performance and cycle service life of the aqueous zinc-iodine battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. An anode material of the aqueous zinc-iodine secondary battery, which comprises composite material of the anion exchange fibre/resin and iodine that is prepared by mixing the anion exchange fibre/resin and iodine according to mass ratio of 1: 0.5 to 2 in water, the adding amount of water is 10 to 50 times of the total amount of two substances, then soaking for 1 to 12h under the condition of 25 to 60degrees Celsius, after soaking, using vacuum pump for filtering, and using distilled water and ethanol to wash in turn, vacuum drying the washed product for 1-12h at 50-80degrees Celsius, drying to obtain the composite material of anion exchange fibre/resin and iodine. 2. A positive electrode material containing the positive electrode material, where positive electrode is prepared by coating the positive electrode material on the current collector. 3. A method for preparing positive electrode, which involves mixing conductive agent and bonding agent, adding N-methyl pyrrolidone or distilled water and stirring uniformly to obtain the anode material slurry, adding amount of the N-methyl pyrrolidone or distilled water is 10 to 40 % of the total weight of the three materials, coating the anode material slurry obtained in step a on the current collector, drying, rolling, cutting to obtain the anode.
