Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic films, in particular to a device for testing the sol properties of aluminum-plastic film packaging. Background Art

[0002] Aluminum-plastic film soft-pack lithium batteries have the advantages of light weight and high specific energy. They are widely used in the energy storage and kinetic energy markets. Their safety issues are a major factor affecting the application of soft-pack lithium batteries. The sol performance test of soft-pack lithium battery packaging is an important criterion for judging the packaging effect of lithium batteries. At present, the sol test mainly involves manually tearing and peeling off the packaged aluminum-plastic film, and visually observing whether the tearing interface is uniformly white. However, the aluminum-plastic film has a strong edge bonding force, and it takes a lot of effort to tear it manually, which makes it difficult to use manual force. A large number of tearings can easily cause the risk of injury to operators. In addition, the tearing angle is unstable, and the variability will affect the sol performance judgment result, which is not conducive to the operation and inspection of production personnel.
