Description

Technical Field

[0001] The invention relates to the technical field of lithium ion battery manufacturing, in particular to a lithium ion battery sealing and shaping fixture. Background Art

[0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is embedded and de-embedded between the two electrodes. When charging, Li+ is de-embedded from the positive electrode and embedded into the negative electrode through the electrolyte. The negative electrode is in a lithium-rich state. The opposite is true during discharge. In recent years, with the increasing severity of the energy crisis and global environmental problems, the development and application of new energy has become a global trend. Lithium-ion power batteries using lithium iron phosphate as the positive electrode material are regarded as the best energy source for new energy vehicles such as electric vehicles and hybrid vehicles. They are developing rapidly. With the advancement of lithium-ion battery technology and the emergence of new materials, lithium-ion batteries are much safer than previous lithium-ion batteries. At present, lithium-ion batteries During the first charging process, gas will be generated, and the generated gas will not be completely discharged from the inside of the battery, and may cause the battery to swell, so the battery must be evacuated and degassed before sealing, and the battery must be shaped. In the production process of lithium-ion batteries on the market, the battery must first be evacuated and degassed in a vacuum box, and then the battery is transferred from the vacuum box to seal.
