Battery Cell Bonding
Bonding cells together can insulate and protect electric vehicle (EV) and hybrid vehicle (HV) batteries from movement and vibration.
Bonding Solutions for Electric Vehicle Battery Cells
To provide insulation and protection against vibration and movement during the manufacturing process and throughout the life of the battery, cells within the battery pack or module need to be bonded together.
Depending on the battery design, cells also need to be bonded to a frame or cold plate. This helps dissipate thermal activity and keep contaminants out of the battery pack.
Bonding application sometimes varies by cell type.
- Cylindrical cells are bonded to a polycarbonate carrier with two component or UV-cure acrylics.
- In prismatic cells, adhesive is dispensed in between each cell
- In pouch cells, hot melt pressure sensitive adhesive (PSA) is used to bond cells together and to frames or a cold plate.
