The invention discloses a renewable zinc electrolysis method based on an echelon power battery and a light and heavy zinc oxide preparation method, and belongs to the field of energy storage. The preparation method of the light and heavy zinc oxide comprises the following steps: by taking roasted ash and secondary zinc oxide as raw materials, adding hydrochloric acid and sulfuric acid to react to obtain zinc chloride and zinc sulfate suspension; carrying out physical solid-liquid separation on the suspension; removing heavy metal ions to obtain zinc chloride and zinc sulfate clear liquid; adding different amounts of sodium carbonate solutions to obtain zinc carbonate and zinc hydroxide; and drying and calcining zinc carbonate and zinc hydroxide to obtain heavy and light zinc oxide. According to the method, the roasted ash and the secondary zinc oxide are used as raw materials, high recycling value and economic benefits are achieved, meanwhile, heavy and light zinc oxide can be prepared ...
