Electrochemical cell presenting two current output terminals on a wall of its container

A cell comprises a container and two current output terminals made of copper situated on a single wall of the container. Each of the current output terminals presents a shoulder. A first terminal is secured to the wall by laser welding, and a second terminal is secured through the wall by crimping with axial displacement of material. The invention facilitates operations of installing and maintaining cells connected together within a module by copper bars. It avoids damaging connections by repeated screwing and unscrewing of nuts screwed onto the terminals when using a screw-and-nut connection system for connecting to the bars.
