What is the production process of cylindrical rechargeable battery 18650 3.7v?
Cylindrical lithium battery production process flow
Objectively speaking, the lithium battery production process is divided into three major sections, one is pole piece production, the other is cell production, and the third is battery assembly. In the lithium battery production process, pole piece production is the foundation, battery core production is the core, and battery assembly is related to the quality of the finished lithium battery. The specific steps of the lithium battery production process include positive electrode slurrying, negative electrode slurrying, positive electrode sheets, negative electrode sheets, steel case assembly, liquid injection and testing, and packaging.
As we all know, the production process of rechargeable battery 18650 3.7v is quite complicated. After all, the safety performance of lithium-ion battery products is directly related to the life and health of consumers. Naturally, the production and manufacturing of rechargeable battery 18650 3.7v has high requirements on the performance, accuracy, stability and automation level of the equipment. .
Take the preparation of electrode slurry in the lithium battery production process as an example. This link is the most front-end link and the most important link in the entire production process. After all, the electrode slurry mixing and dispersion process has an impact on product quality of more than 30%. %. What's the reason?
Causes of liquid leakage in cylindrical rechargeable battery 18650 3.7v
The main reasons are: excessive internal pressure and unqualified external packaging.
1. During the battery manufacturing process, if the following problems occur, it is easy to cause battery leakage:
1. When welding the battery casing and the cap, the welding is not firm, not sealed, there are leaks, weak welds, cracks, cracks and other problems in the welds.
2. When sealing with steel balls, the size of the steel balls is inappropriate and the material of the steel balls is different from the material of the cap.
3. The positive electrode of the cap is not riveted tightly and has gaps, and the elasticity of the insulating sealing gasket is inappropriate, not corrosion-resistant, and prone to aging.
2. Problems that may occur during use:
1. The battery is not original, the voltage is too high or the current is too large
2. The battery is often bumped during normal use, damaging the aluminum-plastic film, and the internal strength of the battery is insufficient.
