Industrial Laser Solutions for the Battery Industry
The world is moving away from fossil fuel dependency, causing a rapid rise in the demand for lithium-ion batteries. Laser technology is a pillar in this transition, helping the battery industry improve its cost-effectiveness, production cycle times, and battery performance. As a green technology, lasers also help lower the environmental footprint.
Anyone in the battery industry can benefit from laser technology, whether it’s for electric vehicles, energy storage, or cleantechs. Fiber lasers are used to clean, texture, weld, and mark a wide variety of battery components, such as:

Laser Applications in the Battery Industry
 |
Laser Welding for Busbar to cell connection at high rateWith its high flexibility, precision, and speed, laser welding is an increasingly popular and proven method, especially for the most recent processes in the battery industry. Welds can be sized and shaped to fit into small spaces, allowing for a wider range of module designs. As a non-contact process, laser welding can reach small battery areas that are often not accessible with ultrasonic bonding and resistance welding. |
 |
Laser Cleaning Before Bonding and WeldingBatteries include thousands of welds and bonded components that are critical for the operation of the battery. A good bonding and welding performance starts with a good surface preparation. Laser cleaning is a highly precise, consistent, and fast process that removes contaminants from metal surfaces, such as electrolytes, dust, oils, and oxides, while leaving the battery components intact. |
 |
Laser Texturing for Thermal and Structural AdhesivesLaser texturing is a key technology for battery structural resistance and cooling systems. Creating specific textures and roughness on metal surfaces improves surface properties before assembly. This results in better heat transfer for thermal adhesives and better bonding performance for structural adhesives. A more efficient heat transfer also improves the battery’s cooling speed, which leads to a faster charging speed. Laser texturing can also be performed at the same time as laser cleaning for complete surface preparation in a single step. |
 |
Laser Marking for Permanent TraceabilityLaser marking is a fast, precise, and consistent process that creates permanent markings for traceability. Serial numbers, data matrix codes, and other types of identifiers can be etched within less than 100 milliseconds. Electrodes inside cylindrical cell batteries can be marked on the fly on conveyors to validate each step of the production process. Cell casings benefit from laser marking for quality control and to reduce the size of any recall. |
 |
Surface Preparation before bonding/gasketingBattery packs are encased in gasketed components, where achieving top-notch welding and gasketing performance relies on meticulous surface prep. Laser cleaning stands out as a precise, reliable, and swift method, removing various contaminants like electrolytes, dust, oils, and oxides from metal surfaces while maintaining battery integrity. This thorough pre-gasketing prep notably boosts bonding strength and sealing effectiveness. |
 |
Increase bonding properties of cooling plates and tubesLaser surface preparation on battery cooling plates and tubes amplifies adhesive bonding strength, ensuring robust and enduring connections. By optimizing surface roughness and cleanliness, laser treatment enhances adhesion reliability, minimizing the risk of delamination over time. This precision method fosters superior heat dissipation efficiency, bolstering battery performance and longevity. |
