Laser cutting technology is the future development direction of lithium battery processing
As the power engine of new energy vehicles, lithium batteries determine the endurance and mileage of new energy vehicles. The quality of their processes directly affects the performance of new energy vehicles. To this end, companies are also experimenting with more advanced processing techniques, such as laser processes, to improve power battery performance.
Laser cutting has always been one of the most widely used laser processing applications. Pulsed lasers are suitable for metallic materials, continuous lasers are suitable for non-metallic materials, and the latter is an important application area for laser cutting technology.
Compared with traditional machining, lithium battery laser processing has the advantages of no tool wear, flexible cutting shape, edge quality control, higher precision and lower operating cost, which is beneficial to reduce manufacturing costs, increase production efficiency, and significantly shorten new Product die cutting cycle.
The lithium battery processing process requires high precision, controllability and quality of the processing machine. In the process of using the die cutter, wear and tear will inevitably occur, and dust and burrs may be dropped, which may cause dangerous problems such as overheating, short circuit and explosion of the battery. In order to avoid danger, it is more suitable to use laser processing. Compared to traditional machining, lasers have the advantage of machining without tool wear, flexible cutting shapes, edge quality control, higher accuracy and lower operating costs.
Compared with the traditional die-cutting method, high-power, on-line laser cutting has no consumables, which greatly reduces the cost. In addition, the processing speed is faster and the production efficiency can be greatly improved. Third, the flexibility is high, and the size in the production process can be freely controlled. .
The mature laser cutting technology in the production and processing of lithium batteries still needs a long test period. At the same time, non-polluting, no consumables, and faster laser cleaning have begun to replace traditional chemical methods, which are used in the production of lithium batteries, which will become the future development direction of the lithium battery industry.
The manufacture of lithium-ion batteries is closely linked by process steps. In general, the production of lithium batteries includes three parts: pole piece manufacturing, cell manufacturing, and battery assembly. Among these three large processes, laser cutting is one of the key processes.
As the core component of new energy vehicles, lithium batteries directly determine the performance of the vehicle. With the gradual outbreak of the new energy vehicle market, laser cutting machines will have great market potential in the future.
