Abstract

We report the synthesis of spent cathode carbon (SCC) with a NaF interface from aluminum electrolysis, and its application as a Na metal anode host. The SCC anode exhibits superior ion conductivity and a high shear modulus. The natural NaF interface on the SCC anode can regulate Na+ transmission and inhibit dendrite growth. Furthermore, the anode can be used to turn waste into treasure through directly using spent cathodic carbon without any chemical processing. The green SCC electrode exhibits a higher flat voltage and better reversibility compared with purified cathode carbon without NaF.
