Problems solved by technology
However, after vacuum packaging and molding, the soft-packed lithium battery will generate gas again in the subsequent production process due to various reasons, which is the most common cause of poor production of soft-packed lithium batteries.
Some flat-packed soft-packed lithium batteries have been screened by reactivation or discharge tests, and their performance is the same as that of normal batteries. However, it is difficult to remove the gas inside the packaged soft-packed lithium batteries.

Abstract
The invention discloses a method for repairing an inflated aluminum-plastic film packaged lithium battery using a double-station double-cavity packaging machine. The double-station double-cavity packaging machine is equipped with a control circuit board, a first cavity, and a second cavity , and a workpiece transfer mechanism, the first cavity is provided with a first controlled heating upper head, a first controlled heating lower head, and a first controlled vacuuming mechanism, and the second cavity is provided with There is a second controlled heating upper head, a second controlled heating lower head, and a second controlled vacuuming mechanism, and it is characterized in that the method for repairing the inflated aluminum-plastic film packaged lithium battery includes inflated aluminum-plastic film packaged lithium battery The first unpacking process, the workpiece transfer process, and the post-packaging process, this case is convenient and fast for repairing, and has good practicability.
Description
[technical field] [0001] The invention relates to a method for repairing a lithium battery packaged with an inflated aluminum-plastic film using a double-station double-cavity packaging machine. [Background technique] [0002] Compared with other types of batteries such as lead-acid and nickel-cadmium, lithium-ion batteries have the advantages of large capacity, high operating voltage, fast charging speed, wide operating temperature range, long cycle life, small size, and light weight. Lithium-ion batteries have been widely used in mobile phones, notebook computers, power tools and other fields, and their application range is becoming wider and wider. [0003] At present, lithium-ion batteries are most widely packaged in aluminum-plastic film flexible packaging, and flexible packaging lithium batteries have great advantages over batteries with other packaging structures. The structure of the soft-pack lithium battery is packaged with aluminum-plastic film. In the event of a...
