The invention relates to a lithium ion battery pole piece forming processing method. Processing of a lithium ion battery pole piece is completed through cooperation of a workbench, a feeding device, a blanking device, a cutting device and a discharging device. The lithium ion battery pole piece forming processing method can solve the problems that when an existing battery pole piece processing device is used for manufacturing a battery pole piece, generally, only one pole piece can be processed through one-time blanking of the existing device, and when the existing device is used for processing pole pieces with different shapes of positive and negative poles, a mold needs to be replaced, so that the pole piece processing process is tedious, the manufacturing efficiency of the battery pole pieces is reduced, after a plate is blanked into a pole piece by the existing battery pole piece processing device, the blanked pole piece needs to be taken down in a manual mode, so that the plate is conveniently blanked again by the existing battery pole piece processing device, and the pole piece blanking processing efficiency is low due to a manual blanking mode.
Description
technical field [0001] The invention relates to the technical field of manufacturing lithium-ion batteries, in particular to a method for forming and processing lithium-ion battery pole pieces. Background technique [0002] The positive electrode material of the lithium-ion battery is lithium metal, and the negative electrode is carbon. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte, and the carbon as the negative electrode has a layered structure. , there are many micropores on it, and the lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are embedded, the higher the charging capacity is, and the pole piece is an important part of the battery. It is divided into positive pole piece and negative pole piece. , the pole piece is simply the core of the battery. When making...
