The transition to a sustainable and circular economy places batteries at the forefront of decarbonization efforts and renewable energy adoption. However, the increasing demand for batteries brings significant challenges, including environmental impacts, resource limitations, and ethical concerns regarding raw material sourcing and end of life strategies. To address these issues, the Battery Passport has been introduced as a digital framework to enhance transparency, traceability, and accountability across the entire lifecycle. By providing detailed data on materials, manufacturing processes, carbon emissions, and end-of-life strategies, the Battery Passport supports informed decision-making and ensures compliance with regulations such as the EU Battery Regulation (2023/1542).
