Description

Technical Field

[0001] The invention relates to the technical field of battery manufacturing, and in particular to a battery plate softening device. Background Art

[0002] At present, the processing of nickel-hydrogen secondary cylindrical battery plates generally involves first making the positive and negative electrodes into rectangles, and then winding the positive and negative plates and diaphragms together through winding equipment and inserting them into a cylindrical steel shell. However, since the plates are generally rolled from foamed nickel-filled positive electrode materials, the plates are hard and brittle and are easier to break. When winding, the surfaces of the plates are prone to cracking, coarse cracks, burrs, or direct fractures. And if the burrs reach a certain height, they will pierce the diaphragm during winding, causing a short circuit or a micro short circuit, thereby reducing the performance of the battery. For this reason, it is necessary to reduce the hardness of the plates and soften the plates before winding to ensure that no coarse cracks and burrs are generated during winding. At present, there are some softening equipment on the market that can better soften the plates, but cracks and burrs often appear after winding, and the overall effect is not ideal. For this reason, there is an urgent need to find a device that can effectively soften the plates. Summary of the invention
