Abstract: The invention relates to an electrochemical element and a battery comprising one or more electrochemical elements, with integrated sensors and/or actuators, in particular including an application for monitoring the operation of an electrochemical element or a Li-ion battery, and/or triggering actions in such an element or such a battery, intended to secure the element or the battery. The electrochemical element (1) comprises a closed shell (2) defining an internal volume and a beam (3) arranged therein having alternating positive and negative electrodes respectively connected to two positive and negative electrical output terminals housing separators, the beam (3) being impregnated with electrolyte and further connected by connection means (4) to one (5) of the electrical output terminals. It further comprises one or mote self-powered sensor and/or actuator elements (20 to 24) each arranged in contact with one component selected from the shell (2), the beam (3), the connection means (4), and the output terminal (5), and capable of measuring a physical or chemical magnitude relative to, and/or generating a physical action or effect on, the surroundings thereof.

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.
