Cell to Cell and Cell to Frame Bonding

Inside prismatic or pouch module designs, cells are firmly bonded to each other to create cell stacks and to provide insulation and protection against vibration or movement.

These stacked cells and other electronic devices are then bonded to a cooling plate to provide good thermal conductivity and dialectic strength. In many cases, the module is then sealed closed in lightweight polycarbonate or ABS enclosure to protect against outside contaminants.

Cell to Carrier Bonding and Module Encapsulation

Cylindrical cells are often bonded to a polycarbonate carrier during module assembly. This holds the cells stationary through the tab welding process and provides structural integrity to the module.

Most often with cylindrical cell modules, a foaming adhesive is applied between the cells to create a lightweight buffer between the cells to provide increased shock and vibration performance and helps to prevent thermal runaway/propagation events.

Gap Filling

Thermal interface materials or gap fillers are dispensed between the modules and the cooling circuits on the battery pack. These viscous adhesives have highly abrasive fillers that are ideal to conduct heat away from the battery.

Pack Seal Pack Seal Pack Seal

Pack Seal

The battery pack is sealed with cure in place gaskets (CIPG) or form in place gaskets (FIPG). The seals are met to an IP68 standard to protect the battery against water intrusions and outside contaminants.

Fire-proof Coating

The cover of the battery pack can be sprayed with a fire-proof coating that not only protects against fire but also protects against corrosion.

Structural Adhesive

Bonding of dissimilar materials as aluminum or other materials is done in battery packs or modules with structural adhesives. This not only contributes to a lightweight design but also offers extra strength and rigidity to the battery.
