Abstract
The invention relates to a device for a lithium electrochemical generator, having an elongate shape along a longitudinal axis (X), comprising a strip comprising a current collector central portion that is at least partially electrically conductive, in which at least one of the two main surfaces is covered with an electrode consisting of a lithium insertion material, and at least two side peripheral portions connected to the central portion and extending transversely to the longitudinal axis, the side peripheral portions being made of an electrically insulating material comprising at least one polymer, the insulating material of at least one of the two side portions being resiliently or plastically deformable, the dimensions of the latter also being determined such as to allow the deformation thereof without breaking during the winding of the strip about a winding axis, which is transverse to the axis (X) and adjacent to the other one of the two side peripheral portions. The invention relates to the method for manufacturing a related bipolar battery.
