Permabond’s patent-pending technology for thermally conductive, expandable battery adhesive filler is getting some attention in the technology magazines on both sides of the pond. Recently ASI (Adhesives and Sealants Industry) and E-Motec (E-Mobility Technology International) have published articles on Permabond’s patent-pending technology.
There aren’t often headlines about EV glue, so why is this new glue getting so much attention? To start with, it isn’t glue or adhesive. It’s a technology that allows Permabond to customize a product that suits each battery manufacturer’s requirements.
Battery manufacturers have a long list of requirements that are difficult to meet with conventional technology. Two competing factors in most battery adhesive technology are weight and thermal conductivity. In many technologies, the higher the thermal conductivity, the higher the weight. The trouble is that battery manufacturers need both – thermal management and lightweight. Good thermal management is essential in battery manufacture. Although lightweight is desired in all vehicles, it is especially important in EVs.
This technology’s foaming, expandable nature creates a lightweight foam that fills all free space in a battery pack. Compression creates a highly conductive skin that transfers heat to the cooling plate when it expands in a closed container. Permabond TC Filler meets all the requirements:
Although this adhesive filler is designed with EV batteries in mind, this technology is ideal for all types of battery packs. Because it is customizable, Permabond can dial in the properties needed for handheld tools, robotic vacuums and lawnmowers, and virtually any battery pack.
