Abstract

The invention discloses a special-shaped lithium battery and a preparation method thereof, include a lithium battery body, A lithium battery body include a positive electrode ear, positive plate, negative ear, A negative electrode sheet, a diaphragm, and a packaging film, A positive tab is connected to the positive tab, The negative electrode lug is connected with the negative electrode piece, thepositive electrode piece is installed on the upper end of the negative electrode piece, and the separator and the packaging film are wrapped and arranged on the exterior of the positive and negativeelectrode piece. The invention adopts a simple way to quickly complete the cutting of the complex abnormal electrode piece and the separator, and compared with the die cutting of the abnormal electrode piece and the electrode piece, the mold opening time can be saved and the mold opening cost can be reduced.

Description

technical field [0001] The invention relates to the field of lithium battery preparation, in particular to a special-shaped lithium battery and a preparation method thereof. Background technique [0002] Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. [0003] In the prior art, only customized molds are used to die-cut pole pieces and diaphragms. Then assembled into corresponding special-shaped batteries. [0004] In the prior art, only customized molds are used to die-cut pole pieces and diaphragms. In this case, it takes a long time to manufacture the mold and a slight adjustment of the size requires changing the mold, so that the cost of the special-shaped battery is very high.
