The global new‑energy industry is experiencing rapid growth, and power batteries—key components of both new‑energy vehicles and energy‑storage systems—are seeing steadily rising market demand. Reducing costs while improving quality and ensuring production safety have become the central challenges driving the entire power‑battery value chain.

Lithium‑ion battery manufacturing involves complex and demanding processes, ranging from electrode sheet fabrication and cell assembly to module PACK integration. These stages demand exceptionally high standards for machining accuracy, process consistency, and yield, making conventional manufacturing methods increasingly ill‑suited to meet the industry’s rapidly evolving production requirements.
 

Laser processing, with its technical advantages of high precision, minimal thermal impact, and non‑contact operation, has become deeply integrated into every stage of power‑battery manufacturing. Leveraging years of expertise in industrial laser technology, Horizon Laser Technology has developed comprehensive equipment and process solutions for the new‑energy lithium‑ion battery industry—covering laser welding, laser cleaning, and laser marking. These solutions are suitable for standalone use on lithium‑battery production lines and can also be seamlessly integrated into automated assembly lines, helping to accelerate the localization and technological upgrading of China’s lithium‑battery sector.

In the cell‑manufacturing process, laser equipment can perform critical operations such as tab welding, casing seal welding, explosion‑proof valve welding, and pre‑weld cleaning of sealing nails. Laser cleaning efficiently removes surface oil and oxide layers, minimizing defects like weld spatter and cold cracks; laser welding, when applied to highly reflective dissimilar metals like copper and aluminum, enables precise control of heat input, reducing the risk of thermal distortion and ensuring the hermeticity and safety of the battery‑cell package.

As production transitions to module and PACK stages, Horizon’s handheld and platform‑type laser welding systems can perform welding on busbars, CCS components, and battery pack housings. Laser marking enables the engraving of unique identifiers on cells and modules, ensuring complete traceability of production data and meeting the quality‑traceability requirements throughout the entire lifecycle of power batteries. Meanwhile, laser cleaning is suitable for pre‑weld surface preparation of battery components and for removing oxide scale from weld seams after welding, replacing sandblasting and chemical cleaning while offering a more environmentally friendly solution that aligns with clean‑production standards in lithium‑ion battery manufacturing facilities.

In the face of the surging expansion of lithium‑battery production capacity, Horizon Laser continuously refines its equipment’s stability and process‑compatibility, catering to both large‑scale automated lines in major lithium‑battery plants and the prototype‑development and flexible‑production needs of small and medium‑sized new‑energy enterprises. With easy integration and low operation‑and‑maintenance costs, our solutions help customers optimize production takt time, boost first‑pass yield, and effectively reduce overall manufacturing costs.
 

As energy storage and the new‑energy vehicle industries continue to expand, the value of laser processing in the power‑battery sector will be further unlocked.

Shenzhen Horizon Laser Technology is deeply committed to the R&D and manufacturing of laser equipment, offering a comprehensive portfolio that spans welding, cleaning, cutting, and marking systems. The company provides lithium‑battery manufacturers with free sample‑testing services and tailored process solutions, working hand in hand with the new‑energy industry chain to drive quality improvement and operational efficiency.
