CR1220 battery

　　Innovation in laser welding process for CR1220 battery modules

　　Power batteries are the core components of new energy vehicles and directly determine the performance of the entire vehicle. Its production process can be divided into front-end, middle-end and back-end equipment. The accuracy and automation level of the equipment will directly affect the efficiency and consistency of the battery.

　　Data shows that the total demand for power lithium batteries will reach 37GWh in 2020, more than ten times that of 2015. The expansion of CR1220 battery production will directly drive equipment demand. As a midstream equipment linking upstream raw materials and downstream products, laser welding technology has begun to enter the industry's vision.

　　For CR1220 battery manufacturers, in short, laser welding is an integrated manufacturing process that integrates raw materials such as positive and negative electrode materials, separators, and electrolytes into whole parts. It is a key process in the entire CR1220 battery production process. All raw materials are welded into battery cells and PACK modules, which can be directly used in traditional consumer electronics, electronic tools, electric bicycles, energy storage power stations and new energy vehicles.

　　At the highest-level lithium battery industry event in China and even the world, Wang Jin, general manager of Han's Laser Precision Welding Division, gave a speech titled "Innovation in Laser Welding Process for CR1220 battery Modules".

　　In fact, the battery manufacturing process involves a wide range of welding technologies, such as ultrasonic welding, resistance welding and laser welding. The reasonable selection of welding methods and processes directly affects the production cost, quality reliability and safety of use of the battery.

　　As a very important process in battery production, laser welding has a great impact on the consistency, stability and safety of the battery. Power batteries have many laser welding parts, the process is difficult, and the welding process requirements are higher. Through efficient and precise laser welding, the safety, reliability and service life of automobile power batteries can be greatly improved, which will surely provide an important guarantee for the development of automobile power technology in the future.

　　Wang Jin introduced that the advantages of laser welding include small loss of welding materials, small deformation of the welded workpiece, stable equipment performance and easy operation, and high welding quality and automation. Its technological advantages are unmatched by other welding methods.

　　Han's Laser is one of the world's major laser processing equipment manufacturers, ranking among the top three laser companies in the world and ranking first in domestic laser equipment share.

　　The company provides domestic and foreign customers with a complete set of laser processing solutions and related supporting facilities. Its main products include laser marking machine series, laser welding machine series, laser cutting machine series, high-power laser cutting and welding equipment and more than 200 series. A variety of industrial laser equipment and its supporting products.

　　As we all know, in the manufacturing process of lithium batteries, there are dozens of processes that require welding, so lithium battery companies have a large demand for welding equipment. With its strong R&D capabilities, Han's Laser has entered the lithium battery industry very early and has a high reputation and good market reputation in this industry.
