| 摘要 |
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. The invention is particularly applicable for the production of electrical energy storage units such as super-capacitors, batteries or generators. |
