The invention relates to a method for producing a negative electrode, to a negative electrode, to a galvanic cell, and to uses of the galvanic cell. According to the method, a coating which contains or consists of a polymer and/or ceramic particles is applied onto the upper face of a flat metal structure which does not consist of lithium, and a metal arrester is applied onto the lower face of the flat metal structure, said arrester having a plurality of openings in the direction of the metal structure. The metal arrester is then pressed into the metal structure by exerting a mechanical pressure, whereby the openings of the metal arrester are filled with metal of the metal structure at least in some regions. The method is simple and inexpensive to carry out and facilitates the production of a negative electrode which has a high energy density at the cell level and a high degree of chemical, electrochemical, and mechanical stability, and thus a high degree of cycle stability, and which allows high operating currents.

The present disclosure relates to a stacking machine, comprising a stacking table, a material-unloading mechanism, a stacking mechanism, a deviation correction table and a conveying mechanism. The deviation correction table can move between the stacking table and the conveying mechanism. In the process of transferring the pole piece to the stacking table, the material-unloading mechanism obtains the pole piece on the conveying mechanism and moves toward the deviation correction table, the deviation correction table moves toward the conveying mechanism, and when the material-unloading mechanism is moved above the deviation correction table, the pole piece may be placed on the deviation correction table. Next, the material-unloading mechanism returns to its position, and the deviation correction table moves toward the stacking table while performing deviation correction on the pole piece. At the same time, the stacking mechanism moves toward the deviation correction table, and when the stacking mechanism moves above the deviation correction table, the pole piece on the deviation correction table may be obtained. The stacking mechanism places the obtained pole piece on the stacking table, then the deviation correction table moves toward the conveying mechanism to prepare for the transfer of the next pole piece. It can be seen that the routes of the material-unloading mechanism and the stacking mechanism may be significantly shortened, so that the stacking pace of the pole piece
