Abstract: A method for producing an electrochemical bundle of a lithium battery, such as an Li-ion battery, with a view to electrically connecting same to the output terminals of the battery, wherein it includes the combination of two steps of folding an electrochemical bundle of a lithium battery which are carried out separately, i.e. a radial folding with plastic deformation and an axial compacting, which make it possible to obtain two separate areas on at least one, and preferably both, of the lateral ends of the bundle. The invention also concerns a method for producing an electrical connection part between the electrochemical bundle and one of the output terminals of the battery, and an associated current collector.

Abstract: A tunnel effect transistor includes a channel made of an intrinsic semiconductor material; source and drain extension regions on either side of the channel, the source extension region being made of a semiconductor material doped according to a first type of doping P or N and the drain extension region being made of a semiconductor material doped according to a second type of doping opposite to said first type of doping; source and drain conductive regions respectively in contact with the source and drain extension regions; a gate structure including a gate dielectric layer in contact with the channel and a gate area arranged such that the gate dielectric layer is arranged between the gate area and the channel; and an area doped according to the first type of doping inserted between the channel and the drain extension region.
