Battery Assembly Technology in the Nordics : Exploring Opportunities and Challenges for Equipment Manufacturers

Abstract: This thesis investigates the opportunities and challenges in battery assembly technology for tool manufacturers in the sectors of e-mobility and energy storage systems in the Nordics. The research aims to understand how equipment manufacturers can contribute to the advancements of batteries and their assembly, ultimately fostering innovation and sustainability in these industries. The background and context of the study highlight the rising importance of battery technology in the Nordics, driven by the growing demand for e-mobility and energy storage solutions. The objectives of the thesis focus on identifying the current battery assembly methods, factors driving the choice of assembly methods, and the challenges and opportunities for innovation in assembly technology. A mixed-methods approach was employed, combining a literature review, surveys, and interviews with key industry players and experts. The collected data were analysed to identify patterns, trends, and relationships related to the research questions utilizing Thematic analysis on interview results and data visualization on survey results. The findings reveal that tightening, adhesives, and laser welding are the most common battery assembly methods in the Nordics, with automation being favoured for high-volume production. Factors such as production volume, product complexity, cost considerations, quality requirements, and available expertise drive the choice of assembly methods. The study also highlights challenges related to adaptability to new tech, cost and flexibility, safety, and environmental sustainability in terms of serviceability, recyclability, and reusability, while opportunities lie in advanced automation, modular assembly approaches, and improved recyclability. The conclusion emphasizes the role of equipment manufacturers in contributing to battery advancements through compliance with regulations, collaboration with industry stakeholders, and leveraging competition for innovation and quality improvement. The study's significance lies in providing valuable insights and guidance for battery assembly equipment manufacturers, promoting market growth, and facilitating sustainable development in the e-mobility and energy storage sectors.
