Driven by the "double carbon" goal, the energy storage industry is ushering in explosive growth. As the core energy storage unit, the upgrade of its manufacturing process has gradually become the focus of the industry. SUMMUS laser welding technology is becoming one of the core technologies of energy storage battery production due to its zero thermal damage, high precision and no pollution.

one,High anti-material stable welding, SUMMUS new solution

Most of the welding parts of energy storage batteries use high-reflection materials such as aluminum and copper, which puts forward higher requirements for the operation stability and process adjustment flexibility of the laser. SUMMUS Xinhe Laser has launched a flexible adjustable beam of light for energy storage panels and battery applications, equipped with key small core diameter lasers, with anti-high reflection technology and ring dynamic light spot output technology, which can greatly improve the stability of laser equipment and welding process quality, and effectively ensure the process quality of energy storage panels.

two,SUMMUSEnergy storage boardSpecific applications, details reflect quality

Battery cover welding.The shell materials of the energy storage board are mainly aluminum alloy and stainless steel, among which the three-series aluminum alloy is the most used. The use of traditional continuous fiber laser welding can easily cause spatter, pores and other problems, which have a great impact on the stability and reliability of the energy storage board.

SUMMUSXinhe laser annular light spot welding technology, an optical fiber outputs two coaxial beams of light, the central beam of light is mainly deep-penetration welding, and the outer ring beam of light minimizes the kinetic energy of the overflowing steam, stabilizes the molten pool, and reduces the temperature layer. At the same time, high-speed welding can more effectively reduce spatter, and the weld is formed flat and beautiful.

At the same time, with the 6.0 control system, different trajectories of welding can be realized, which can expand the molten pool, stabilize the keyhole, and contribute to gas overflow, making the welding process more stable and minimizing spatter and pores.

Lithium battery welding. For batteries, the smoothness of the connection between the batteries determines the performance of the battery. Most batteries are made of copper and aluminum, both of which are high anti-material. During the welding process, the quality and energy density of the laser beam of light have extremely high requirements. When the quality and energy density of the laser beam of light do not meet the requirements of welding, there will be problems such as impervious welding, weak welding, poor consistency before and after welding, and bubbles in welding, which will affect the performance of the entire battery module unit.
