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 an expanding aluminum-plastic film package lithium battery repairing method for a double-station and double-cavity packaging machine. The double-station and double-cavity packaging machine is provided with a control circuit board, a first cavity, a second cavity and a workpiece transfer mechanism, wherein a first controlled heating upper head, a first controlled heating lower head and a first controlled vacuum supply mechanism are arranged in the first cavity; a second controlled heating upper head, a second controlled heating lower head and a second controlled vacuum supply mechanism are arranged in the second cavity; and the expanding aluminum-plastic film package lithium battery repairing method for the double-station and double-cavity packaging machine is characterized by comprising a first unpacking process, a workpiece transfer process and a post packaging process of an expanding aluminum-plastic film package lithium battery. The expanding aluminum-plastic film package lithium battery repairing method is convenient and efficient to repair and good in practicability.
Description
[technical field] [0001] The invention relates to a rework method for a lithium battery packaged with an inflated aluminum-plastic film in 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 safet...
