Description

Technical Field

[0001] The utility model specifically relates to a cutting tool for square shell batteries. Background Art

[0002] At present, the common method of disassembling the battery is to use a knife to make a scratch on the square shell battery, and then use pliers to tear off the shell along the scratch. For example, when disassembling and analyzing a hard square shell battery, it is necessary to make a scratch around the battery at about 2 to 3 mm and 5 to 7 mm away from the positive and negative electrode covers of the square shell battery, and then use pliers to roll up and tear off this part of the battery shell along the scratch, so that the battery cover and shell can be separated in this way.

[0003] However, this method is time-consuming and laborious, and the depth of the scratch is difficult to control and completely depends on the operator's experience. If the scratch is too shallow, it is difficult to separate the outer shell and the cover cell. If the scratch is too deep, it is easy to damage the battery cell inside the battery. If the internal cell is damaged when disassembling a fully charged battery, it is easy to cause a short circuit and fire, causing safety problems. In addition, it is dangerous to use a knife to operate, and safety accidents are prone to occur. For this reason, we propose a cutting tool for square shell batteries. Utility Model Content
