This expert note examines the need for a Battery Aadhaar system in India to enable battery traceability, circularity, and data transparency across the battery value chain. As battery demand rises with the growth of electric mobility and renewable energy, India faces increasing challenges related to critical mineral dependence, resource efficiency, and end-of-life battery management. The note highlights how a digital battery identity framework can support responsible sourcing, lifecycle tracking, reuse, recycling, and informed decision-making for manufacturers, regulators, recyclers, and consumers. Drawing from global battery passport initiatives and India’s evolving digital public infrastructure ecosystem, the note outlines pathways for developing a domestic battery data management framework. It further discusses data governance, technology systems, regulatory requirements, stakeholder coordination, and business models needed to build an interoperable, secure, and scalable Battery Aadhaar for India’s clean energy transition.
