Summary: This work investigates the root cause of failure with Li metal as the ultimate anode when using conventional/composite separators and/or porous anodes. A feasible route of utilizing Li metal is presented. The study reveals that Li(+) flux passing through the conventional separator is not uniform, resulting in preferential Li plating/stripping, and that porous anodes alone are subject to clogging with moderate- or high-loading cathodes. Therefore, the synergy between the separator and anode pair is necessary to deliver delocalized Li+ and uniformly plate Li metal over the large surface areas of the porous anode.
