Abstract

To provide an aluminum battery that extends its lifespan and maintains superior conductivity.SOLUTION: An aluminum battery of the present invention comprises a positive electrode, a negative electrode, a separator, and an electrolyte. The positive electrode comprises a metal substrate and a coating layer. The coating layer is formed on a metal substrate, and the coating layer material comprises conductive carbon material and water-soluble conductive polymer, with a layer count of five or fewer layers. The separator is positioned between the positive electrode and the negative electrode. The electrolyte is impregnated into the separator, the positive electrode, and the negative electrode.SELECTED DRAWING: Figure 1
