The invention provides a lithium battery, a battery cell and an assembly method, and relates to the technical field of lithium batteries, the lithium battery comprises a shell, a negative collector plate, a battery cell, a positive collector plate, an insulating sheet and a positive cover plate; one end face of the negative collector plate is welded at the bottom of the inner side of the shell, and the other end face is welded with a cell cathode; the battery cell positive electrode is welded with the positive electrode collector plate, and the positive electrode cover plate is welded with the positive electrode collector plate; the insulating sheet is arranged between the battery cell and the positive electrode cover plate; and the shell is provided with a roller groove, the roller groove forms a convex edge on the inner side of the shell, and the convex edge is in contact with the insulating sheet. By means of the lithium battery, the current collecting disc and the battery cell do not need to be connected in a welding mode, the current collecting disc and the battery cell are tightly pressed through the roller groove of the shell, and the assembling efficiency of the lithium battery is improved.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, and relates to machine welding technology and lithium battery assembly technology, in particular to a lithium battery, a battery cell and an assembly method. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses non-aqueous electrolyte solution. With the development of microelectronics technology in the 20th century, miniaturized equipment is increasing, and it is widely used in mobile phones and notebook computers. , Electric tools, electric vehicles, backup power supply for street lamps, aviation lights, and small household appliances. [0003] Most of the existing lithium batteries are lithium batteries in the form of two poles. The two ends of this type of lithium battery are the positive electrode and the negative electrode. The two ends are respectively equipped with a positi...
