Daoke Dao Laser Welding for Automotive EV Battery Cell Spacers: Heat-Resistant & Stable

Date：2026-01-19 14:36 Source：daokedao Browse：20

Automotive EV battery cell spacers require heat-resistant welding to maintain cell spacing and thermal management. Traditional spacers easily deform under high temperatures, causing cell short circuits. Daoke Dao plastic laser welding equipment ensures spacer stability. Suitable for modified PP and PA materials, the welds are stable at -40°C to 130°C, withstanding battery operation heat. The strong welds maintain spacer rigidity, ensuring uniform cell spacing (±0.1mm). The non-contact process avoids damage to battery cells. Compliant with automotive battery standards (IEC 62133), the equipment integrates into automated battery assembly lines, with a welding speed of 2 spacers per second. It supports different cell sizes (pouch/prismatic), with quick fixture adjustment. The welds resist electrolyte corrosion, ensuring long-term reliability. Daoke Dao supports new energy vehicle manufacturers. Contact us for thermal stability test results.
