Today’s lithium-ion batteries (LiBs) are found in more than half of the hybrid-electric and plug-in hybrid vehicles on the marked, all-electric vehicles, and nearly all consumer electronics. As a result, recycling of LiBs will be a strategic necessity in the near future. In the present study, the conventional aluminium recycling process (secondary aluminium production) is suggested as a suitable process for treatment of LiBs. The overall idea is to recover aluminium, copper and lithium from a mixed waste stream of LiBs and aluminium scrap. A two-stage process, consisting of a preheating step and a melting step, were tested on smartphone batteries mixed with pure aluminium in a ratio 1:10 and the distribution of elements between the metal phase, the slag phase and the off-gas evaluated. The obtained results are compared and discussed based on the thermodynamic calculated by the use of the FactSage™ software version 7.
