The Main Defects of Using Lithium Battery Slitting Knives

Published On: August 13, 2020

The lithium battery slitting knife is a kind of carbide circular blade, and it also has a variety of models, mainly used for cutting lithium battery pole pieces. The cutting of a lithium battery pole piece is a very important and basic step in the production process of lithium batteries. Lithium battery slitting blades are widely used because of their superior performance, but every coin has two sides, and lithium battery slitting knife use also has certain defects.


The main defects of using lithium battery cutting blades are as follows:

The first is the glitch, which is a common situation in all metal processing. Especially metal glitches, which are so harmful to lithium batteries, and metal glitches with size cracks pierce directly, shorting the positive and negative electrodes. To avoid this situation, it is most important to find the most suitable lateral pressure and tool overlap according to the nature and thickness of the pole pieces when adjusting the knife. Careful operation and attention to the value during use can also effectively reduce the appearance of burrs.


Besides, curling is another situation that often occurs during use, which is very harmful to lithium battery pole pieces. Defects of carbide lithium battery slitting blades use also include other aspects. Due to the different use methods and materials, the lithium battery pole piece slitting knife also has different failure modes. Here are the main ones. Here are the three most important and most common. Next, this passage will talk about the main failure modes of lithium battery slitting knife.

In the process of cutting pole pieces, a slippery machine needs to be operational for a long time, so it is necessary for lithium battery slitting blades to have effective properties, such as weight, production technology, and wear resistance. Carbide lithium battery slitting blades have a certain life span during continuous operation. In general, the most common failure during use mainly consists of fatigue failure, adhesive wear, and abrasive wear.


Lithium-ion battery pillar fabrication is a key process in the battery fabrication process, including slurry preparation, pole coating and drying, pole blank compaction, and pole cutting. Therefore, be careful during lithium battery slitting knife use, pay attention to the cutting angle and pressure, and carefully control the value to ensure the cutting quality. In addition, also pay attention to the meticulousness of the workpiece, and be careful when cutting.
