Laser Welding Machine for Lithium-ion Batteries

As new energy vehicles gain popularity, the demand for lithium-ion batteries continues to rise. To maintain the quality and stability of these batteries, precise welding of core components is essential. Common soldering methods include spot welding, wire welding, and laser welding. Among these, the laser welding of EV batteries represents a cutting-edge technology known for its accuracy and efficiency.

Part 1: Welding Technologies for Lithium Batteries

1. Spot Welding: This is a prevalent welding technique that employs resistance heating to join electrodes and tabs. Spot welding is quick and yields quality results, but it requires high surface quality on the components being welded.

2. Seam Welding: This technique softens two metal sheets through heating before tension is applied to connect them, making it suitable for larger battery components with enhanced durability.

3. Laser Welding: Utilizing a high-energy laser beam, laser welding instantaneously melts and connects electrodes and tabs, delivering a high welding speed, minimal heat-affected zones, and superior quality; however, the equipment cost can be higher.

4. Tin Soldering: This method connects battery components using molten solder, predominantly used for smaller elements that require proper alloy and process controls.

Choosing the appropriate welding technique based on specific requirements ensures the quality and efficacy of the battery pack.

Part 2: Reasons to Employ Laser Welding for Lithium-Ion Battery Packs

Laser welding harnesses the exceptional focus and high energy density of laser beams. When concentrated on a small area, this creates a highly intense heat source that instantaneously melts the materials being welded for robust junctions.

Utilizing laser welding for lithium-ion battery packs is advantageous for several key reasons:

High Welding Speed: This process is rapid, vital for mass production as it prevents slowdowns that might limit output.

High Precision: Laser welding provides precise joining of components, ensuring consistently high bond quality. Control over weld penetration depth and width enables the attainment of desired production outcomes. The welds formed possess high strength and robust mechanical properties, crucial for the reliability of electric vehicle batteries.

Non-Contact Approach Minimizes Damage: As a non-contact technology, laser welding lessens risks of damaging battery components, which is critical for maintaining the integrity of battery packs and minimizing thermal influence on cells.

Enhanced Conductivity: The performance of e-mobility batteries depends significantly on electrical conductivity. Laser welding ensures a high-quality conductive connection, maintaining low resistance and stable current transfer, and thus boosting the overall performance of lithium batteries.

Dissimilar Metal Welding Capabilities: Given the variety of metals often present in lithium-ion batteries, such as copper and aluminum, laser welding excels at joining these dissimilar metals due to its ability to counteract interface reactions, making it ideal for such applications.

Surface Contaminant Removal: Laser welding's local high-energy heating can effectively eliminate surface contaminants, ensuring clean welding surfaces that promote quality and reliability.

Automation and Versatility: Laser welding integrates well with automated production lines, reducing labor demand while allowing flexibility to adapt to varying component sizes and shapes.

In the evolving lithium battery sector, laser welding stands as a flexible, precise, and efficient method fulfilling production performance demands, establishing itself as essential equipment for lithium-ion battery welding.

Advantages of Battery Laser Welders

Resistance welding, laser welding, and Micro TIG welding are prominent techniques used in battery production. Here are some advantages of choosing laser welding for lithium-ion battery packs:

Welding Speed: Both resistance and laser welding provide quick welding processes, but laser welding can require more intricate handling. Micro argon arc welding, conversely, is slower but suitable for high-quality connections.

The Galvo lithium battery laser welding machine boasts high efficiency, exceeding ordinary systems by at least threefold. With many customizable configurations, our laser equipment supports advanced battery designs, meeting high production demands.

When selecting a laser welding solution, both pulsed and continuous modes are available, depending on the specific application and welding criteria. Refer to the article: Introduction of EV battery laser welding process for insights into pulse and QCW laser options.

Welding Quality: Laser welding features a small heat-affected zone and fine seam characteristics, ensuring high-quality welding results. Resistance welding outputs may fluctuate, while Micro argon arc welding can generate robust connections but involve larger heat impacts.

Equipment costs can be higher for Battery Laser Welding Machines, necessitating significant investment compared to more commonly available resistance and argon arc welding alternatives.

Part 3: Laser Welding Use in Battery Pack Assembly Lines

Laser welding technology is integral to the fabrication and interconnection of battery cells, including battery casings.

1. Laser Welding Battery Cells and Tabs

Common battery tab materials comprise aluminum for positive electrodes and nickel or nickel-plated copper for negatives. Welding battery tabs to poles must ensure robust connections alongside smooth welds. Using fiber lasers with exceptional beam quality facilitates stable electrode column welding and minimizes spatter, fostering improved welding quality.

2. Lithium Battery Module and Pack Soldering

Connections between power batteries are typically achieved by welding the adapter pieces to individual batteries, mostly using copper and aluminum for the electrodes. This emphasizes laser welding for effective junctions.

3. Laser Welding the Lithium Battery Case

Casing materials primarily include aluminum alloy and stainless steel. Particularly, aluminum alloys are predominant, requiring laser welding technology for tasks such as battery pack enclosures and sealing operations. Continuous laser use in casing welding can boost efficiency by 5 to 10 times while enhancing appearance and sealing quality, making laser welding machines vital in battery casing manufacturing.

Part 4: Laser Technology Applications in Battery Production

Laser Welding

Laser technology has broad applicability in the electric vehicle and battery sector. Renowned companies like Tesla, LG, BYD, and Panasonic have embraced laser welding in their production, enhancing manufacturing efficiency and quality while fostering industry innovation.

Laser Cleaning

To maintain optimal welding conditions, battery manufacturers need to ensure surfaces are contamination-free before and after welding. High-power laser cleaning machines proficiently remove coatings and oxides, improving overall weld quality.

Laser Marking

Utilizing fiber laser marking machines enables high-contrast markings on lithium battery packs, including clear QR codes and branding elements, thereby enhancing visibility and brand impact.

Cost of Battery Laser Welding Machine

Investing in a laser welding machine entails substantial acquisition and maintenance costs; however, leveraging a laser equipment manufacturer’s expertise provides an invaluable return on investment by enhancing production efficiency and quality, while also reducing labor costs.
