Toward a cell-chemistry specific life cycle assessment of lithium-ion battery recycling processes

Mohr, M.; Peters, J. F.; Baumann, M.; Weil, M.

Abstract:
On the basis of a review of existing life cycle assessment studies on lithium‐ion battery recycling, we parametrize process models of state‐of‐the‐art pyrometallurgical and hydrometallurgical recycling, enabling their application to different cell chemistries, including beyond‐lithium batteries such as sodium‐ion batteries. These processes are used as benchmark for evaluating an advanced hydrometallurgical recycling process, which is modeled on the basis of primary data obtained from a recycling company, quantifying the potential reduction of environmental impacts that can be achieved by the recycling of different cell chemistries. Depending on the cell chemistry, recycling can reduce significantly the potential environmental impacts of battery production. The highest benefit is obtained via advanced hydrometallurgical treatment for lithium nickel manganese cobalt oxide and lithium nickel cobalt aluminum oxide‐type batteries, mainly because of the recovery of cobalt and nickel. Especially under resource depletion aspects, recycling of these cells can reduce their impact to an extent that even leads to a lower “net impact” than that of cells made from majorly abundant and cheap materials like lithium iron phosphate, which shows a more favorable performance when recycling is disregarded. ... mehr
