Laser With Lithium Battery, The Mainstream Of Future Battery

With the continuous development of national science and technology, technological electronic products and new energy vehicles are also constantly launching new era products.

As we all know, the concept of new energy vehicles has repeatedly swept the capital market, attracting consumers' attention to batteries and energy storage. With the introduction of concepts such as "carbon peak, carbon neutrality" and "lucid water and lush mountains are golden mountains and silver mountains", lithium batteries, the core components of new energy vehicles, have been welcomed all over the world. The reason why lithium batteries are popular all over the world is due to their advantages such as long life, fast charging, light weight, and high energy density. Based on these advantages, lithium batteries are gradually replacing traditional batteries such as lead-acid.

According to the "New Energy Vehicle Industry Development Plan (2021-2035)" issued by the General Office of the State Council on November 2, 2020, it is estimated that by 2025, the sales of new energy vehicles in China will reach about 20% of the total sales of new vehicles. Judging from the current data, there is a lot of room for growth of lithium batteries in the future.

As a new type of clean energy, lithium batteries can power many types of vehicles, such as new energy vehicles, electric trains, golf carts and other different types. There are more than a dozen steps in the production of a lithium battery, and today we will focus on the laser welding process.

The role of the laser welding machine is to provide customers with a complete set of lithium battery production equipment to ensure the battery life and safety can run without obstacles. Compared with traditional welding methods such as argon arc welding and resistance welding, laser welding has obvious advantages. The energy of laser welding is concentrated, the welding efficiency is high, the processing precision is high, the speed is fast, and the depth-to-width ratio of the weld is large. Due to the small heat input of the laser beam in laser welding, the heat-affected zone is small, the residual stress and deformation of the workpiece are small, and the welding is precise. Because the battery cell of the power battery adheres to the principle of "lightness", its welding material is generally thin aluminum alloy, and its shell and cover are generally less than 1.0mm. The basic material thickness of the usual battery manufacturers is about 0.8mm. In order to weld these thin sheets together, laser welding plays an important role.

It is undeniable that due to the increasing demand for new energy vehicles and lithium batteries, manufacturers' demand for laser welding machines is also increasing.

Fly laser welding equipment is mainly used in the welding of new energy lithium battery packs: lithium battery to nickel, explosion-proof valve welding, battery lug welding, power battery shell and cover plate sealing welding, large monomer square shell lithium battery and large Polymer power battery module pack welding, etc., provide a better complete set of automatic welding solutions for the majority of new energy lithium battery welding enterprises.
