The battery industry is in undergoing rapid development with the objective of achieving a status of circular economy. To this end, it is essential to ascertain the subsequent fate of manufactured batteries, including their destination and the source from which they originate. Conversely, the transfer of the necessary information from the manufacturer to the recycler must be conducted in a secure and expedient manner. This will facilitate the implementation of a selective and purposeful recycling process that is dependent on the battery chemistry, for example. In this context, we present newly researched approaches for tracing and sorting batteries and battery materials within the scope of design for circularity. The underlying technologies can be directly implemented into a battery passport environment, thereby providing the necessary data to the relevant parties within the battery circularity landscape.
