Abstract: An asymmetrical supercapacitor including an alkaline electrolyte, at least one separator, at least one positive electrode including a nickel-based hydroxide and a nickel-based current collector, and at least one negative electrode including a nickel-based current collector and having a porous three-dimensional structure. Some pores are open, the mean diameter of the open pores being greater than or equal to 100 μm and being less than or equal to 300 μm and two contiguous open pores (1, 2) communicate by at least one opening (5) the mean diameter of which is greater than or equal to 35 μm and less than or equal to 130 μm. The three-dimensional structure includes a mixture including at least one activated carbon, at least one electron-conducting additive, and a binding agent including at least one elastomer polymer and at least one thickening polymer.
