Embodiment approach 1
[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0025] figure 1 It is a diagram showing a schematic structure of the metal negative electrode (negative electrode for battery) 10 of the first embodiment. figure 1 (a) is a three-dimensional view, figure 1 (b) is a cross-sectional view. Metal negative electrode 10 such as figure 1 As shown, active material layers 12 are formed on both sides of the current collector 11. The current collector 11 is arranged at the center of the thickness direction of the active material layer 12 so that when the metal negative electrode 10 is used in a battery, the electrode distance between the metal negative electrode 10 and the positive electrode of the battery is kept constant.
[0026] The current collector 11 transfers electrons between the active material layer 12 and the battery terminal (not shown). Examples of the material of the current collector 11 include copper alloys ...
Embodiment approach 2
[0052] In the second embodiment, a more specific method will be described with respect to the elution step described in the first embodiment. In the method of the second embodiment, the battery is assembled using the metal negative electrode 10 before the elution step in which the polarization step has been completed, and an electrolyte is injected into the assembled battery. In this case, the auxiliary agent 122 is eluted in the electrolyte solution injected into the battery, thereby forming a space 125 in the active material layer 12 of the metal negative electrode 10. In addition, when the method of the second embodiment is used, in the completed battery, the components of the eluted auxiliary agent 122 are contained in the electrolyte.
[0053] Furthermore, a battery using the metal negative electrode 10 of the present invention can be used as a metal-air battery, and examples thereof include zinc-air batteries, magnesium-air batteries, aluminum-air batteries, and iron-air ba...
Embodiment approach 3
[0059] In the third embodiment, a more specific method will be described with respect to the elution step described in the first embodiment. In the method of the third embodiment, a battery is assembled using the metal negative electrode 10 after the elution step in which the elution step has been completed, and an electrolyte is injected into the assembled battery. When the method of the third embodiment is used, the components of the eluted auxiliary agent 122 are not included in the electrolyte in the completed battery.
[0060] In the method of the third embodiment, the material of the auxiliary agent 122 and the type of the solution used in the elution step can be made the same as those of the second embodiment. That is, the solution can be the same alkaline aqueous solution as the electrolytic solution, and the auxiliary agent 122 can be a material that elutes in the alkaline aqueous solution. However, in the third embodiment, the types of materials and solutions of the au...
