Battery Pack Assembly Applications

Dispensing 1-part or 2-part materials for the sealing or bonding of cell modules to the overall battery pack assembly

Ensuring a battery cell module provides enough power with the correct form and fit for the end product is no simple task. Typically, numerous modules are placed together to create a larger assembly of modules, or a pack. The shape of these packs varies greatly depending on the vehicle, or storage battery’s overall shape and are usually bonded together to reduce vibration problems or sealed to prevent corrosion issues due to moisture.

Battery Pack Bonding

Methods:

  • Bead bonding: Beads of material are precisely applied to the face of each module, arranged side by side, and then compressed. Uses less material, but requires robotic application.
  • Flood: Material is dispensed to the base of the entire pack, to bond each module in place. Simplifies robotic needs, but utilizes a greater volume of material.

Common Materials Dispensed:

  • Single component epoxies
  • Two component curing epoxies

Common Challenges:

  • Volume of bead or flood requires a large meter, that can be difficult to mount to a robot
  • Nordson Solution: Our range of continuous flow meters are utilized, mounted directly to most robots. Larger shot meters can also be installed at the base of the robot, where the dispense valve is placed directly on the robot arm. 

Battery Module Sealing

Methods:

  • Bead completely surrounding the battery module
  • Bead placed between a top and bottom cell module

Common Materials Dispensed:

  • Single component epoxies
  • Two component curing epoxies

Common Challenges:

  • Bead be accurately dispensed in the correct location, to ensure assembly compression does not overflow into battery cells, or outside of pack
  • Nordson Solution: Specially designed nozzles or needles for precision application in difficult to access channels / locations.
