3.7v polymer lithium battery is qualified

According to the following points, a preliminary judgment can be made on the unqualified and qualified products of the 3.7v polymer lithium battery:
First, what is the problem with the floating powder on the pole piece of the 3.7v polymer lithium battery?
There is floating powder on the pole pieces of the 3.7v polymer lithium battery. After being wound into the battery and injected, the floating powder will move in the battery with the movement of the electrolyte, moving to some problematic places, such as defective diaphragms. Locally, it may cause problems such as micro-short circuit and large self-discharge of the battery.

Second, what is the problem with the thickness and thinning of the pole piece of the 3.7v polymer lithium battery?
The thickness of the electrode sheet of the 3.7v polymer lithium battery does not meet the requirements. First, the thickness of the battery will not meet the requirements. In addition, the thickness of the electrode sheet is different, and the micropores in the active material will be different. The difference in the amount of electrolyte absorbed by the pole pieces during filling will cause differences in battery performance.

Third, what impact will the short circuit of the 3.7v polymer lithium battery have on the battery?
The short circuit of the 3.7v polymer lithium battery cell will cause the battery formation to fail, and the finished battery can only be scrapped

Fourth, what effect will the spiral shape of 3.7v polymer lithium battery have?
The spiral shape of the 3.7v polymer lithium battery will affect the size of the battery cell, cause difficulties when loading the packaging film, and may also cause a short circuit.

Fifth, what impact will the 3.7v polymer lithium battery's pole piece have on the battery?
The pole piece of the 3.7v polymer lithium battery has the possibility of piercing the diaphragm, making the positive and negative electrodes contact, causing a short circuit in the battery.
