At present, the existing battery generally adopts an all-electrode lug type positive electrode and an all-electrode lug type negative electrode, namely, a part of area (positive electrode smooth foil area) which is not coated with slurry is reserved at one end edge when positive electrode slurry is coated on a positive electrode current collector (generally aluminum foil), and a part of area (negative electrode smooth foil area) which is not coated with slurry is reserved at one end edge when negative electrode slurry is coated on a negative electrode current collector (generally copper foil). After the positive plate, the negative plate and the diaphragm are wound to form the electric core winding body, the foil body of the positive optical foil area forms a positive electrode tab position end face, and the foil body of the negative optical foil area forms a negative electrode tab position end face. The end face of the pole lug position needs to be welded with the current collecting plate so that the current of the battery can be output from the current collecting plate. The foil-shaped body of the pole lug end face is thin (6-30 microns), soft and easy to deform, when the foil-shaped body is welded with the current collecting plate, the whole foil-shaped body is bent or deformed by applying pressure, the diameter of the pole lug end face of the core winding body is enlarged or protruded, the core winding body cannot be installed in a battery shell or is communicated with the battery shell to cause short circuit, the end face is deformed and unsmooth due to the fact that the pressure is directly applied to the end face of the foil-shaped body, a local area of the end face cannot be in contact welding with the current collecting plate, the welding area is small, the welding strength is low, the internal resistance of the battery is large, and therefore the pole lug end face of the core winding body needs to be shaped before the current collecting plate is welded.
The existing shaping method of the electric core winding body mainly comprises the following two methods:
1. the foil-shaped body of the positive electrode optical foil area and the foil-shaped body of the negative electrode optical foil area are pre-cut into strip shapes by laser respectively, and after the positive electrode plate, the negative electrode plate and the diaphragm are wound into an electric core winding body, the strip-shaped foil-shaped bodies are welded on a bottle cap-shaped current collecting disc. The shaping method needs to use laser to cut the foil body into strip shapes, has complex process, low efficiency and high cost, the strength of the body of the foil body after being cut into the strip shapes is low, the foil body is easy to be broken when being welded on a current collecting disc, and the shaping method has small bearing current compared with the original foil body and can be done with half the effort.
2. The invention patent with the patent number of CN102683634A and the patent name of 'a large-capacity cylindrical lithium ion battery and a production method thereof' adopts a high-frequency oscillation (such as ultrasonic wave) mode to shape the end face of a pole lug position of the lithium ion battery, and a tuner of a machine adopted by the method has high manufacturing cost, limited service life, complex frequency debugging of the corresponding tuner and long frequency adjusting time.
Based on the defects of the two shaping methods, a method and a device for shaping the end face of the battery core coil with higher efficiency, simpler processing, lower cost and longer service life are needed to be found so as to improve the production method of the lithium ion battery.
