Abstract: The invention relates to a method of producing electrical connections for an electrical energy storage unit (10), said unit employing at least one electrical energy storage element (70) placed inside a casing (20?), said casing having at least one cover (30, 40) containing the electrical energy storage element (70) in a main body (20) of the casing, said element (70) and said cover (30, 40) each having a current collector means, which method is characterized in that it includes at least one step of depositing gallium on one or other of the current collector means and a step of assembling two current collector means separated by the gallium coating followed by a diffusion brazing step carried out by the disposition and the pressing of a mass heated to a given temperature on the unit formed by two current collector means, the unit being brazed for a given time in order to produce the electrical connection for the electrical energy storage unit.

Abstract: The invention relates to an electric energy storage component comprising a coil winding and at least one connector (100, 200) including a plate (100) which is in contact with a plurality of said coils, wherein the plate of the connector has a surface which is provided with a terminal (200) wherein the shape thereof is essentially that of a revolution, wherein the plate (100) also forms a series of bosses (120, 125) extending in a raised manner along a surface of the plate opposite to the that containing the terminal (200). The invention is characterized in that the terminal (200) has at least one inner recess (210) and in that at least one boss (100) penetrates into said recess (210).
