    摘要： The invention concerns an asymmetric supercapacitor comprising an alkaline electrolyte, at least one separator, at least one positive electrode comprising a nickel hydroxide and a current collector made from nickel, and at least one negative electrode comprising a current collector made from nickel and having a porous three-dimensional structure in which:• pores are open, the average diameter of the open pores being greater than or equal to 100 micrometres and being less than or equal to 300 micrometres; and • two contiguous open pores (1, 2) communicate via at least one opening (5) of which the average diameter is greater than or equal to 35 micrometres and less than or equal to 130 micrometres. The porous three-dimensional structure comprises a mixture comprising at least one activated carbon, at least one electrically conductive additive, and a binder comprising at least one elastomer polymer and at least one thickening polymer. The invention also concerns a method for producing an asymmetric supercapacitor with an alkaline electrolyte.
