Lithium-ion battery manufacturer analyzes lithium-ion battery processing method and lithium ion battery laser processing. Lithium-ion battery processing process is high in accuracy, controllability, and processing machines. To prevent danger, use lasers for processing more suitable.

This paper, the lithium-ion battery manufacturer analyzes lithium-ion battery processing methods and lithium-ion battery laser processing technology. Lithium-ion battery processing method Lithium ion battery processing, extensive application field, meeting domestic and foreign test requirements. 1.

Treatment of the negative electrode material First, the large particle size and ultrafine powder are separated from the required particle size, preventing chemical reactions, and improving the safety of lithium battery. The method of improving the surface porosity of the material can increase the capacity of 10%, and when the C / A is constant, the safety performance of the lithium ion battery can also improve. 2.

Controlling the pulping process of the pulping process generally uses special chemical reagents to minimize the tension between the positive and negative slurry. Improve compatibility between groups, preventing the material in the agitation process "reunion". The voids between the coating time base material and the nozzle should be maintained below 0.

2 mm or less, and the surface of the polar plate is smooth, and the surface of the surface is smooth, depressed, scratched. The storage time of the slurry is maintained for 6 hours, and it is ensured that there is no self-phenomenon in the slurry. The uniform slurry is the uniformity of the distribution of the substrate of the positive and negative electrode of the lithium ion battery, and improves the consistency of the battery.

Lithium-ion battery laser processing technology is more suitable for processing of laser in order to prevent danger. Compared to traditional machining, laser advantage is that processing has no tool wear, flexible cutting shape, edge quality control, higher accuracy and low operating costs. Related to traditional die-cutting methods, high power, online laser cut-free consumables, greatly reduced costs; Freely control.

Lithium-ion battery as the core component of new energy vehicles, directly determines the performance of the vehicle. With the gradual outbreak of the new energy vehicle market, the laser cutting machine will have a large market potential in the future. Because of its own technical advantages, laser processing technology, the use of laser welding, polar material cutting, marking, etc.

in the battery cell and module of the lithium-ion battery industry, etc.
