Fiber lasers have become the mainstream application in the field of power batteries
The continuous improvement of power battery performance forces the upgrade of intelligent manufacturing of lithium battery equipment, and IPG lasers are widely used in the power battery industry for cell and module welding, cleaning before welding, and pole piece cutting.
Fiber lasers have become the mainstream application in the field of power batteries.
Fiber laser technology is currently mainly used in laser welding of batteries, poles, flexible connections, liquid injection holes, explosion-proof valves, modules, and tabs in the production process of power batteries; laser cutting, cleaning, and drilling of tabs and poles Hole, carving and other links.
Laser welding is one of the most important process links in the production process of power batteries. Compared with traditional lasers, fiber lasers have obvious advantages in terms of improving efficiency, saving energy, service life, providing precision and manufacturing technology.
From June 10th to 11th, Gaogong Lithium Battery and Gaogong Industrial Research will hold the 13th High-Tech Lithium Battery Industry Summit at the Hyatt Hotel in Shenzhen Airport. “Industry Reshaping”, over 600 corporate executives will jointly conduct in-depth discussions on the trends and changes in the power battery industry in 2020.
As the sponsor of this summit, Apache (Beijing) Fiber Laser Technology Co., Ltd. (IPG) National Key Account Sales Manager Jiang Baowen will give a keynote speech on “Application of Fiber Laser in Power Battery Industry”, sharing the power of fiber laser Innovative exploration and application in the battery manufacturing process.
IPG is a global leader in high-power fiber lasers and amplifiers. It is a company that can fully control the performance, cost and production of active fiber and semiconductor pump diode, the core technology of fiber lasers.
The continuous improvement of power battery performance forces the upgrade of intelligent manufacturing of lithium battery equipment, and IPG lasers are widely used in the power battery industry for cell and module welding, cleaning before welding, and pole piece cutting.
IPG’s competitive advantage in the field of fiber lasers is mainly reflected in four aspects: superior product performance + rich product line, stable product quality, low cost of use and perfect after-sales service.
Jiang Baowen told Gaogong Lithium that the current battery companies have put forward higher requirements for lasers in terms of stable output, suppression of spatter during welding, and penetration detection.
In response to the requirements of battery companies, IPG has developed YLS-AMB series of adjustable beam mode lasers and LDD-700 welding whole process monitoring system and other new products.
Specifically, the YLS-AMB series of adjustable beam mode lasers can provide a total output power of up to 25 kW, and automatically adjust the output beam mode parameters. A central beam with a core diameter of 50μm can provide a total output rate of up to 9kW, and a central beam with a core diameter of 100μm can provide a total output power of up to 12kW.
Jiang Baowen pointed out that the YLS-AMB series lasers can almost achieve spatter-free welding, greatly improving welding efficiency and quality, and improving battery product performance.
At the same time, the LDD-700 welding whole process monitoring system developed by IPG can realize welding seam tracking and working distance measurement before welding; real-time penetration monitoring during welding and welding seam quality after welding. Improve the welding quality of fiber lasers.
Currently, fiber lasers have become the mainstream application in the power battery field, and IPG has a major share in the high-end fiber laser market, and has reached cooperation with many power battery companies in China.
