Welding plays a pivotal role in the assembly of battery packs, serving as a critical process in the manufacturing of energy storage systems for various applications, including electric vehicles, portable electronics, and renewable energy storage.
The increasing demand for high-performance, energy-dense batteries has driven innovation in welding technologies to ensure the reliability, safety, and efficiency of battery packs. Traditional methods are being refined and optimized to accommodate emerging battery types like lithium-ion and solid-state battery technologies.
While advancements in welding techniques contribute to the optimization of battery pack performance, challenges persist. Joining dissimilar materials, managing heat input, and minimizing thermal stress during welding are crucial considerations to mitigate the risk of performance degradation and safety hazards. Moreover, ensuring uniform weld quality across large-scale battery production remains a significant challenge that necessitates ongoing research and development efforts.
This presentation will review three welding technologies - resistance welding, micro TIG welding, and laser welding - used in battery pack assembly and provide an overview of the advantages and limitations of each of the technologies for various manufacturing requirements. |
