The automotive industry is experiencing a rapid evolution, with electric vehicles (EVs) taking center stage. The continued adoption of EVs depends on reducing costs, developing a robust charging infrastructure, and designing efficient and durable battery packs with longer-range and fast-charging capabilities. Adhesives are emerging as a critical component in the design and assembly of high-performing EV battery packs, as automakers strive to match the cost and efficiency of internal combustion engine vehicles.
EV battery pack design is constantly evolving as automakers and researchers work towards boosting performance, cutting costs, and enhancing sustainability. The focus is on increasing energy density and reducing the cost per kWh, which has led to simpler designs that remove parts, weight, and bulk. Advanced adhesive technology is being utilized to develop solutions for challenges such as structural support and complications in battery replacement, disassembly, and recycling, in order to propel EV battery pack designs into the future.
Different designs such as Cell-Module-Pack (CMP), Cell-to-Pack (CTP), and Cell-to-Body (CTB) are being explored in the evolution of EV battery technology. Each design has its own advantages and challenges, with automakers seeking solutions with fewer parts to improve energy efficiency and simplify production. Adhesives play a crucial role in these designs by providing structural support, enhancing thermal management, and improving safety in the event of crashes.
Adhesives offer a range of benefits that make them vital to EV battery production, including enhanced performance, increased design flexibility, optimized energy management for safety, added structural capability, optimized thermal management, support for zero-emission EVs, and improved manufacturing processes. With the growing adoption of cell-to-body designs, adhesives can provide the bonding strength necessary to replace modular walls and support structures, while also optimizing thermal management to prevent overheating during battery charging and operation.
