An automatic lithium battery assembly line is a fully integrated system that streamlines the production of lithium-ion batteries. It uses advanced automation technologies to handle processes such as cell sorting, welding, stacking, packaging, testing, and quality inspection. By reducing manual intervention, it ensures higher efficiency, consistent quality, and faster production rates—making it ideal for large-scale battery manufacturing.

A lithium battery assembly line typically includes:

• Cell Sorting Machines – for classifying cells by capacity, voltage, and resistance.

• Laser Welding Systems – for precise and reliable connections.

• Stacking & Assembly Machines – for prismatic, pouch, or cylindrical battery modules.

• Battery Management System (BMS) Integration Equipment – for monitoring safety and performance.

• Aging & Formation Equipment – for charging/discharging cycles to stabilize battery performance.

• End-of-Line (EOL) Testing Systems – for quality validation before delivery.

Semco provides end-to-end battery assembly solutions with all these components seamlessly integrated.

A prismatic battery assembly line is specifically designed for manufacturing prismatic cells, which are rectangular in shape and widely used in electric vehicles (EVs), energy storage systems, and portable electronics. This line includes equipment for cell stacking, case assembly, laser welding, electrolyte filling, sealing, and testing. Semco’s prismatic assembly lines are tailored for high precision and scalability to meet the growing EV and ESS demand.

A Battery Energy Storage System (BESS) assembly line differs from a standard battery assembly line in its scale, design, and integration requirements. While a regular line focuses on cell or module-level assembly, a BESS line is designed for large-scale module and pack assembly, including:

• High-capacity prismatic/pouch/cylindrical cells

• Battery racks and cabinet assembly

• Thermal management systems integration

• Advanced BMS setup for grid applications

• Safety and reliability testing under energy storage standards

Semco provides custom BESS assembly solutions that support utility, industrial, and renewable energy projects.

An energy storage assembly line is used to manufacture battery packs and modules specifically designed for renewable energy integration, grid stabilization, telecom backup, and industrial applications. These lines ensure high safety, durability, and performance standards, making them essential for the rapid growth of the Energy Storage System (ESS) market.

Battery laser welding is a high-precision welding technique used to join metal components in lithium-ion batteries, such as tabs, busbars, and casing parts. It is important because it provides:

• High-strength and reliable joints

• Minimal heat damage to cells

• Improved safety and performance

• Consistent quality for mass production

Semco’s advanced laser welding systems ensure precise, efficient, and safe connections in battery manufacturing.

Yes, laser welding is suitable for prismatic, cylindrical, and pouch batteries, though the welding method and parameters vary depending on battery design and material type. For high-energy density and safety-critical applications like EVs and ESS, laser welding is the preferred method due to its accuracy and durability.
