Application of laser cutting in new energy lithium battery industry

In recent years, new energy vehicles have sprung up. Compared with traditional fuel vehicles, new energy vehicles use lithium batteries as a power source. Lithium ion battery is a kind of secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. As a new type of clean energy, lithium batteries can not only power new energy vehicles, but also power various products such as electric trains, electric bicycles, and golf carts.

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. Before the advent of laser technology, the battery industry used traditional machinery for processing. Compared with traditional mechanical processing, laser processing has the advantages of no tool wear, flexible cutting shapes, edge quality control, higher accuracy, and lower operating costs. It is conducive to reducing manufacturing costs, improving production efficiency, and greatly shortening new product molds.

Cut cycle 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.
