Laser cutting technology is the future development direction of lithium battery processing

Lithium batteries, as the power engine of new energy vehicles, determine the endurance and mileage of new energy vehicles. The quality of their craftsmanship directly affects the performance of the new energy vehicle market. To this end, companies are also trying to use more advanced processing technology, such as laser technology, to improve the performance of power batteries.

Laser cutting has always been the most widely used technology in laser processing. Pulsed lasers are suitable for metallic materials, and continuous lasers are suitable for non-metallic materials. The latter is an important application field of laser cutting technology.

Compared with traditional mechanical processing, lithium battery laser processing has the advantages of no tool wear, flexible cutting shape, edge quality control, higher accuracy, and lower operating costs. It is conducive to reducing manufacturing costs, improving production efficiency, and greatly reducing new Product die cutting cycle.The lithium battery processing process requires high accuracy, controllability and the quality of processing machines. In the process of use, the die cutter will inevitably wear out, and then drop dust and produce burrs, which may cause dangerous problems such as battery overheating, short circuit, and explosion. In order to avoid danger, it is more suitable to use laser for processing. Compared with traditional machining, laser has the advantages of no tool wear, flexible cutting shape, edge quality control, higher accuracy and lower operating costs.

Compared with the traditional die-cutting method, high-power, online laser cutting has no consumables, which greatly reduces the cost; in addition, the processing speed is faster, which can greatly improve the production efficiency; third, the flexibility is high, and the size in the production process can be freely controlled .

The laser cutting technology in the production and processing of lithium batteries is mature and requires a long test period. At the same time, laser cleaning with no pollution, no consumables, and faster speed has begun to replace traditional chemical methods and applied in the production of lithium batteries, which will become the future development direction of the lithium battery industry.

The production of lithium-ion batteries is closely linked by one process step. Generally speaking, the production of lithium batteries includes three parts: pole piece manufacturing, battery cell manufacturing, and battery assembly. In these three major processes, laser cutting is one of the key processes.

Lithium batteries, as the core components of new energy vehicles, directly determine the performance of the entire vehicle. With the gradual explosion of the new energy vehicle market, laser cutting machines will have great market potential in the future
