Battery Cell Bonding
Cell Bonding Solutions for EV Battery
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.
Cell to Carrier Bonding Stabilizes EV Batteries
In cell to pack bonding – also known as cell to carrier bonding – many cylindrical battery cells are fused onto a plastic carrier, keeping cells stationary at very short distances from each other. This allows the cells to maintain structural integrity while protecting them from vibration and movement during the welding process and life of the product.
Some advantages of Battery Cell bonding to customers are as below:
- Allows the cells to maintain structural integrity
- Provides insulation & protection against vibration
- Helps dissipate thermal activity
- Keeps contaminants out of the battery pack
