Abstract: A method for mixing and dispersing an internal phase and an external phase in a liquid compound. The method includes preparing the compound by combining the internal phase of the compound and the external phase of the compound, the external phase of the compound being a liquid, forming a film of the compound by depositing a first volume of the liquid compound on a rotating surface and collecting the film as a dispersed liquid compound on a collection surface.

Abstract: A battery, including a cathode, an anode, and an electrolyte solution. The cathode includes a cathode active substance and a cathode current collector. The electrolyte solution includes first metal ions and second metal ions. In a charging/discharging process, the first metal ions can be reversibly deintercalated-intercalated at the cathode, the second metal ions can be reduced and deposited as a second metal at the anode, and the second metal can be oxidized and dissolved back to the second metal ions. The anode includes a anode active substance and a anode current collector. A lead-containing substance is provided on a surface of the anode active substance and/or in the electrolyte solution. A mass ratio of lead in the lead-containing substance to the battery is not greater than 1000 ppm.
