The invention relates to a recycling method for Zn and Mn in a waste battery. The recycling method comprises the following steps: firstly, the waste battery is mechanically crushed, then an electrolyte is sorted out manually and dissolved in water, a solution containing Zn ions and Mn ions is obtained and subjected to suction filtration, and a first filter residue and a first filtrate are collected respectively; a solution containing S ions is added dropwise to the first filtrate, the mixture is stirred to react for 10-15 min, a product is filtered, and a second precipitate and a second filtrate are obtained; the second precipitate is dried, and ZnS is obtained; the first filter residue is washed with distilled water, dried and ground into powder, the powder is heated to 440-460 DEG C and kept at the temperature for 25-35 min, and MnO2 is obtained. The recycling method for Zn and Mn in the waste battery has the advantages that cost consumption is low, operation is simple, resources are saved, and energy is reused.
