Before revision:  The use of exclusively abundant materials with comparably low environmental impacts within the cell is the major strength of the  MgS battery , leaving the energy-intensive process steps as the remaining critical contributors to the total environmental impacts i.e., the cell manufacturing and magnesium and aluminium metal production. Here, the use of renewable electricity and non-fossil sources for process heat are the keys for further improving its environmental performance .
After revision:  The use of exclusively abundant materials with comparably low environmental impacts within the cell is the major strength of the MgS battery has significant potential to outperform both existing LIB, and lithium-sulfur batteries .
