Abstract

The invention discloses a lithium battery cell. The lithium battery cell is characterized in that the tail end of an anode piece (1) is connected with the head end of an insulating partition piece (3), the tail end of the insulating partition piece (3) is connected with the head end of a cathode piece (2), the tail end of the cathode piece (2) is connected with the head end of another insulating partition piece (3), the tail end of the other insulating partition piece (3) is connected with the head end of another anode piece (1), joints of the anode pieces (1) and the insulating partition pieces (3) and joints of the cathode piece (2) and the insulating partition pieces (3) are folded to form Z shapes, and connecting branch pieces (4) are branched out of the ends of the anode pieces (1) and the cathode piece (2). The lithium battery cell has the advantages that manufacturing working procedures can be reduced to a great extent, the pieces can be prevented from moving relatively in later packaging periods, and accordingly the performance of lithium batteries can be guaranteed.

Description

technical field [0001] The invention relates to a battery, in particular to a lithium battery cell. Background technique [0002] The battery cell of lithium battery is mainly composed of positive pole piece and negative pole piece. The positive pole piece is generally made of aluminum sheet or the substrate coated with aluminum layer on the surface, and the negative pole piece is generally made of copper sheet or the surface is coated with The substrate of the copper layer is composed of a positive pole piece and a negative pole piece separated from each other and stacked in a device filled with electrolyte to form a lithium battery. In the existing technology, lithium battery cells are generally composed of pieces of positive pole pieces and pieces of negative pole pieces superimposed on each other, and their extremes are opposite. Lithium battery cells with such a structure It is necessary to cut the aluminum sheet and copper sheet piece by piece, and in the lithium batt...
