Abstract: The present disclosure relates to a cell. Since at least a portion of the cathode pole piece located in the bent areas is formed with a broken portion, there is no positive electrode active material layer and thus no lithium ions in the area corresponding to the broken portion, therefore, the amount of lithium ions that can de-intercalate from the cathode pole piece in the bent areas will be significantly reduced. In addition, the present disclosure also relates to a battery and a cell manufacturing apparatus.

Abstract: The present disclosure provides a cell forming apparatus and a cell forming process. Prior to entering a winding device, a device compounds the anode pole piece and the cathode pole piece with a first diaphragm to obtain a first compound material strip. Since the pole pieces are respectively located on two sides of the first diaphragm, the first diaphragm is enveloped between the anode pole piece and the cathode pole piece. During the compounding process, the surfaces on both sides of the first diaphragm will not come into direct contact with the compounding device. Therefore, the adhesive on the surface of the first diaphragm does not adhere to the compounding device, thereby improving the compounding effect of the first diaphragm with the anode pole piece and the cathode pole piece, and thus enhancing the quality of the manufactured cell. In addition, the present disclosure also provides a cell.
