METHOD TO PRODUCE A BATTERY FOR ENERGY STORAGE

Method to manufacture an energy storage battery having the steps of: providing an electrochemical cell, which is at least partially complete and is provided with an electrical collector; providing a container having a first wall; placing, on an outer surface of the first wall, an outer body, which constitutes an electrical pole of the battery; and inserting the electrochemical cell into the container placing the electrical collector close to the first wall; providing the electrical collector with an access from the outside of the container in order to permit a weld between the electrical collector and the outer body in order to establish an electrical connection; welding the electrical collector and the outer body together through the aforementioned access in order to establish an electrical connection.
