The embodiment of the invention provides a pole ear fixing device, a pole ear cap, a battery and a welding method thereof, and is applied to the field of batteries. The pole ear fixing device comprises a fastening part which is used for fastening one end of the battery to be welded. The fastening part is provided with a first limiting hole for passing through a first pole ear and a second limitinghole for passing through a second pole ear. When the fastening part is fastened on the pole ear welding surface on the battery to be welded, the welding end of the first pole ear is bonded to the first electrode of the battery to be welded, and the welding position of the welding end of the first pole ear and the first electrode is exposed through a first welding hole and the welding position ofthe welding end of the second pole ear and the second electrode is exposed through a second welding hole. Therefore, the pole ear fixing device is arranged to fix the first pole ear and the second pole ear, thereby facilitating the welding operation of the first pole ear and the second pole ear.
Description
technical field [0001] The present application relates to the battery field, in particular, to a tab fixing device, a tab cap, a battery and a welding method. Background technique [0002] Based on the power battery module composed of multiple cells, the mainstream solution is to weld the positive electrode at the top of the cell and the negative electrode at the bottom of the cell with the bus bar to form a series-parallel structure. This kind of scheme has high manufacturing cost and lacks industry advantages due to the influence of the general environment. [0003] The existing technology mostly adopts the ultrasonic wire drawing welding process. This technology aims to carry out the busbar assembly and welding process of the battery module on one side of the electrical measurement module, and the processing process is carried out after the module assembly is completed. This technology reduces the material cost of the battery module to a certain extent and improves the e...
