[0002] The existing lithium battery conductive connection structure is to bond the metal sheet on the plastic board. First, the use of adhesive is increased by bonding the metal sheet to the plastic board, which not only increases the manufacturing cost, but also pollutes the environment. In addition, the bonding The direction of the metal sheet on the plastic board is difficult to fix accurately, and it is easy to be crooked, which affects the quality of the connection structure
In addition, when the plastic plate bonded to the metal sheet is inserted into the aluminum shell in the subsequent process, the processing difficulty is increased due to the protrusion of the metal sheet, and there is a risk of short circuit or short circuit

The invention provides a lithium battery with a novel conductive connecting structure. The lithium battery comprises a cell, a novel conductive connecting structure and a battery cover plate in orderconnection; a positive tab and a negative tab are arranged at one side of the cell, the novel conductive connecting structure comprises a plastic plate and a first metal sheet, and a second metal sheet; the first metal sheet and the second metal sheet are located in the plastic plate and located at two sides of the middle of the plastic plate; the upper surfaces of the first metal sheet and the second metal sheet and the plastic plate are the same plane, the positive table and the negative tab are connected with the first metal sheet and the second metal sheet; and the bottom surface of the novel conductive connecting structure without the first metal sheet and the second metal sheet and with an exposed surface is adhered with the battery cover plate in an attachment way. The first metal sheet and the second metal sheet are fused and molded through the plastic resin, after the metal sheets are fused, the connecting structure design is easier to enter an aluminum case, and the bad problems of short circuit or circuit breaking caused by the aluminum case at the connecting part are greatly reduced.
