Abstract

In the field of battery formation and capacity, the present invention proposes a pouch battery formation device in order to improve the easy deformation of pouch batteries during negative pressure formation, which is characterized in that it includes: a base; a negative pressure system, set on the base, It is used to extract negative pressure for the battery; the clamping system is set on the base to clamp the battery when the battery is formed; the power supply system is set on the base to supply power for the battery; the pouch battery formation device of the present invention is applied , can effectively improve the situation that the pouch battery is easily deformed during negative pressure formation; the invention also provides a pouch battery formation method.

Description

technical field [0001] The invention relates to the field of battery formation and capacity, in particular to a soft pack battery formation device and method. Background technique [0002] In the current lithium battery production process, in order to form a uniform SEI film on the surface of the negative electrode carbon material, it is necessary to perform multiple charge and discharge cycles on the produced battery with different parameters. This process is called formation; in the existing battery production process, Formation generally uses multiple current probe assemblies to abut multiple battery lugs placed in the battery tray to supply power to the battery. [0003] In the production process of soft-pack batteries, in order to avoid the problem of flatulence in the produced soft-pack batteries, it is necessary to discharge the gas in the soft-pack batteries after formation, and then seal them. It is easy to deform after being out of air, causing the battery to be s...
