    Abstract: The invention discloses a zinc organic battery having a container. The container contains a positive electrode active material, a positive electrode current collector, an organic solvent, a zinc negative electrode, and an aqueous electrolyte. The organic solvent and the aqueous electrolyte are not miscible and are layered due to different densities. The positive electrode active material has a redox activity, and has the two forms of an oxidized state and a reduced state. If the positive electrode active material itself is a liquid and is difficult to be dissolved in the aqueous electrolyte, then the organic solvent may be omitted. The positive electrode active material itself doubles as the organic solvent and is layered with the aqueous electrolyte. The zinc negative electrode is immersed in the aqueous electrolyte and is not in contact with the organic solvent. The aqueous electrolyte is an aqueous solution containing a zinc salt.
