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

FAQs
Battery cell bonding connects individual battery cells to form a larger pack enhancing the structural integrity and battery performance like in electric vehicles. This bonding ensures cells to be insulated and protected from vibrations and movements during any operation for safety and efficiency.
Cell bonding solutions have multiple benefits including improved insulation against vibrations, flexibility in designs, enhanced durability. Cell bonding is crucial for maintaining performances of EV batteries that ensures the cell remains attached throughout their cycle, reducing manufacturing costs and improving production efficiency.
Battery cell bonding is necessary for creating efficient and strong EV batteries. By using advanced techniques like wire bonding and adhesive applications, manufacturers ensure battery packs perform reliably under multiple conditions and contribute to overall safety and efficiency of electric vehicles.
Materials such as UV-cure acrylics, two component methyl methacrylate adhesives are commonly used in battery cell bonding. This choice of adhesive depends on the applications and designs of battery packs providing strong bonds as well as flexibility to absorb vibrations.
Customization is possible in cell bonding solutions to meet your specific requirements for different types of designs and applications. Patvin Engineering offers tailored solutions considering several factors ensuring optimal performance and reliability in various battery bonding applications.
