ABSTRACT:
A cell contains a device for inserting a stack of electrodes and holding it in place. This device enables a stack of electrodes to be inserted and held in place in a container having a base and receiving a lid, the stack having two opposite plane faces and the container having two opposite plane walls. The device comprises two tapes connected by a central blade and is disposed between the plane faces of the stack and the plane walls of the container. The two tapes form elastic cylindrical sectors, advantageously parabolic in shape, with the concave side facing outwards when fitted.
