Info Sheet: Battery Passports

The Battery Passports Info Sheet defines a battery passport as a digital twin of a physical battery, storing information including the battery’s label, manufacturing history and origin of its materials, battery chemistry, state of health, use history, safe handling and end-of-life (EoL) management. The battery passport is a means to support end-to-end traceability, and provides crucial information for decision-making on repair, reuse, repurposing and recyclability of the battery. A robust and widely accessible battery passport helps provide information critical to removing important barriers to repair, reuse, repurposing, recycling and end-of-life of EV batteries. A wide range of initiatives currently underway at sub-national, national and international levels are summarized in this Info Sheet, along with five key considerations for a fair and equitable battery passport and its relationship to environmental justice.
