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 () comprises a closed shell () defining an internal volume and a beam () arranged therein having alternating positive and negative electrodes respectively connected to two positive and negative electrical output terminals housing separators, the beam () being impregnated with electrolyte and further connected by connection means () to one () of the electrical output terminals. It further comprises one or mote self-powered sensor and/or actuator elements (to) each arranged in contact with one component selected from the shell (), the beam (), the connection means (), and the output terminal (), and capable of measuring a physical or chemical magnitude relative to, and/or generating a physical action or effect on, the surroundings thereof.
