Li primary batteries are currently treated along with other Li batteries in few big pyrometallurgical plants in northern EU countries. Pyrometallurgical processes present negative environmental impacts while hydrometallurgical processing can potentially ensure the integral recovery of all materials in li primary batteries. In this work, preliminary experimental findings obtained in LIFE-LIBAT project (LIFE16 ENV/IT/000389) about cryo-mechanical and chemical treatment of Li(0)-MnO2 batteries were reported.

Li primary batteries are currently treated along with other Li batteries in several big pyro- metallurgical plants in Northern EU countries. Nevertheless, pyro-metallurgical processes do not allow for Mn and Li recycling and present negative environmental impacts, on the other hand hydrometallurgical processing can potentially ensure the integral recovery of all materials in Li primary batteries. In this work, preliminary experimental findings obtained in the LIFE-LIBAT project (LIFE16 ENV/IT/000389) are reported.
