Batteries are adding weight to vehicles in the emerging electric vehicle era. Henkel Corp. is developing weight-saving concepts to offset the addition, by introducing adhesive products to battery structures.
The German chemical, electronics assembly and consumer goods supplier says its Loctite- branded adhesives for constructing battery packs offer a reduction in weight, in addition to dispensing faster, curing in less time and costing less than earlier iterations of industry adhesive-bonding applications.
It's a critical opportunity as automakers switch from using old-fashioned nuts and bolts and welds to other bonding materials.
"Fasteners and rivets are painful to work with," said Pradyumna Goli, Henkel's business development manager for eMobility. "With adhesives and sealants — anything material-based — you get more homogeneous and consistent performance, and you know exactly what to expect."
But that puts new pressure on the supplier.
"Now the adhesives are responsible for the majority of structural integrity. We have to provide the kind of performance these cars would need over their lifetime," he said.
