Product Description

What products do we make?
 

 

Adhesive tape solutions for cell-to-cell bonding

SEPNA's two-component polyurethane thermally conductive structural adhesives for use in EV battery cell-to-cell bonding applications. EV battery cells need bonding solutions that are lightweight, durable, and easy to assemble. They may also need to promote flame retardancy or provide dielectric strength to help the pack operate properly and keep passengers safe.

PU Structural Adhesives

PU Structural adhesives are used in EV battery packs to create bonds that can withstand various environmental conditions and mechanical loads. These adhesives provide shear and tensile strength to increase protection against external forces such as impacts, vibrations, and loads.

With structural adhesives, battery components are stronger together. One such example is the structural battery pack, where batteries become part of the load-bearing structure.

The choice of structural adhesive depends on where it is used. Different adhesives provide different levels of strength and flexibility. The material's compatibility with the adhesive is also a key factor.

Light-weight

Total vehicle weight is tied inextricably to the range of electric vehicles.
The battery pack is a major contributor, typically weighing between 600 and 700 kilograms for the average battery electric vehicle (BEV).

Smart lightweight designs can counterbalance part of this, and Sepna's engineering expertise and partnership with RLE International are fundamental for optimizing aluminum structures per crash standards and passenger safety.

 

Typical Applications
 

 

Where Adhesives Are Used in Battery Modules

Adhesives are used at several locations in battery modules to help dissipate heat, insulate electrical components, seal off against environmental damage, and create strong structural bonds.

Here are common examples of where they are used:

• Cell casings: Adhesives between battery cells help maintain good thermal contact between individual cells, allowing the heat generated during operation to spread evenly. They can also provide a strong and durable bond to distribute the stress load uniformly and improve the vehicle's structural integrity.
• Cooling plates: Adhesives between battery modules and cooling plates facilitate heat transfer to dissipate heat. Newer cell-to-pack designs bond individual cells directly to the cooling plate.
• Enclosures and housings: Adhesives contribute to the robustness of enclosures and housings, providing secure bonds that withstand mechanical stresses and environmental conditions.
• Small components: Adhesives are used to attach small components such as heat spreaders, thermal pads, and sensors. Depending on the attached components, adhesives can provide various benefits, such as better thermal conductivity or insulation.

 
1. The bonding between new energy battery module cells and bottom cases, cells and cells;
2. Bonding of vehicle body composite parts, such as SMC, BMC, RTM, FRP, etc. and metal materials;
3. Self-adhesion and mutual adhesion of metal, ceramics, glass, FRP, plastic, stone, wood and other base materials.

Direction of Applications
 

 

• Beading: Beads are placed on each square battery cell. Once placed in the battery pack, the beads are compressed, creating a larger bonding surface. It uses less material but requires more robotic control.

 

• Encapsulation: Cells are placed into a battery pack, and then the material is dispensed or injected to surround the cells with the sealant material. It uses a large volume of material, but provides the highest confidence of insulation, with limited robotic requirements.

Adhesive Applications in Battery Modules to Cold Plate Bonding

Cold plate bonding involves bonding cells or other electronic devices to a cooling plate. This generally involves a structural bond that provides good thermal conductivity and dielectric strength. These materials are often abrasive and require the right dispensing solution. Two-component polyurethane meter mix with precision control is of critical importance in these applications.
