    Abstract: The invention relates to an electrochemical element (1) comprising: a) a container (2) comprising an opening allowing the introduction of at least one electrochemical beam (7); and b) a closing part (3) for closing said container, comprising: i) at least one flat inner surface (4a, 4b, 4c) which is oriented towards the inside of the container and can be directly electrically connected to a current collector (6), ii) at least one flat outer surface (5a, 5b, 5c) which is oriented towards the outside of the container and can act as a terminal of the electrochemical element, and iii) at least one wall (8a, 8b, 8c) connecting said at least one flat inner surface to said at least one flat outer surface, said wall forming an angle of between 70 and 120° in relation to one of the two flat surfaces. The closing part of the container allows heat dissipation to be improved in the direction of the longitudinal axis of the element.

    Abstract: The invention concerns an electrochemical element and the method for manufacturing same, as well as a battery comprising one or more electrochemical elements, for application in particular in the field of electrochemical elements or Li-ion batteries. The electrochemical element comprises a closed shell (1) defining an internal volume inside which a bundle (2) is arranged, having alternating positive and negative electrodes (3) respectively connected to two positive and negative electrical output terminals and housing separators, the bundle (2) being impregnated with electrolyte. The shell (1) comprises a bottom wall (4) having an internal bottom face (4a), oriented towards the internal volume, and at least one side wall (5, 6) having an internal side face (5a, 6a), oriented towards the internal volume. The internal side face (5a, 6a) joins the internal bottom face (4a) by substantially forming an internal angle (a).
