Method for manufacturing a cell for a secondary battery, the method comprising: - a first operation of unwinding a separator film, - a second operation of depositing a first electrode on the separator film, - a third operation of holding, on the separator film, a first lateral edge and a first longitudinal edge of the first electrode by means of a first holding element, and a second lateral edge opposite the first lateral edge and the first longitudinal edge of the first electrode by means of a second holding element, - a fourth operation of unwinding the separator film in order to cover the first electrode, - a fifth operation of depositing on the separator film a second electrode of opposite polarity to the first electrode, the second electrode being arranged substantially opposite the first electrode, - a sixth operation of holding, on the separator film, a third lateral edge and a third longitudinal edge of the second electrode by means of a third holding element, and a fourth lateral edge and the third longitudinal edge of the second electrode by means of a fourth holding element, - a seventh operation of unwinding the separator film in order to cover the second electrode, - an eighth operation of removing the first holding element and the second holding element, - a ninth operation of removing the third holding element and the fourth holding element, in which method the operations can be repeated a plurality of times, in which method the eighth operation of removal successively comprises a first lateral movement in which the first holding element and the second holding element move along a first axis parallel to the first and second lateral edges (4, 5) and a first movement away in which the first and second holding elements (8, 10) move away from the first electrode or, said eighth operation of removal simultaneously comprises a first lateral movement in which the first holding element and the second holding element move along a first axis parallel to the first and second lateral edges (4, 5) and a first movement away in which the first and second holding elements (8, 10) move away from the first electrode. - a first operation of unwinding a separator film, - a second operation of depositing a first electrode on the separator film, - a third operation of holding, on the separator film, a first lateral edge and a first longitudinal edge of the first electrode by means of a first holding element, and a second lateral edge opposite the first lateral edge and the first longitudinal edge of the first electrode by means of a second holding element, - a fourth operation of unwinding the separator film in order to cover the first electrode, - a fifth operation of depositing on the separator film a second electrode of opposite polarity to the first electrode, the second electrode being arranged substantially opposite the first electrode, - a sixth operation of holding, on the separator film, a third lateral edge and a third longitudinal edge of the second electrode by means of a third holding element, and a fourth lateral edge and the third longitudinal edge of the second electrode by means of a fourth holding element, - a seventh operation of unwinding the separator film in order to cover the second electrode, - an eighth operation of removing the first holding element and the second holding element, - a ninth operation of removing the third holding element and the fourth holding element, in which method the operations can be repeated a plurality of times, in which method the eighth operation of removal successively comprises a first lateral movement in which the first holding element and the second holding element move along a first axis parallel to the first and second lateral edges (4, 5) and a first movement away in which the first and second holding elements (8, 10) move away from the first electrode or, said eighth operation of removal simultaneously comprises a first lateral movement in which the first holding element and the second holding element move along a first axis parallel to the first and second lateral edges (4, 5) and a first movement away in which the first and second holding elements (8, 10) move away from the first electrode. in which method the operations can be repeated a plurality of times, in which method the eighth operation of removal successively comprises a first lateral movement in which the first holding element and the second holding element move along a first axis parallel to the first and second lateral edges (4, 5) and a first movement away in which the first and second holding elements (8, 10) move away from the first electrode or, said eighth operation of removal simultaneously comprises a first lateral movement in which the first holding element and the second holding element move along a first axis parallel to the first and second lateral edges (4, 5) and a first movement away in which the first and second holding elements (8, 10) move away from the first electrode.
