In recent years, there has been increasing interest in lithium metal batteries which utilize lithium plating as an energy storage mechanism. For lithium-metal battery applications, Zhao et al. employed a commercial carbon gas diffusion layer as a host for dual-charge storage by lithium intercalation and plating. Plating occurred on the carbon electrode once the material was saturated with intercalated lithium. These results suggest the potential application of carbon materials as cathodes in the lithium mediated system, due to carbon's ability to plate lithium, although it is expected that there would be efficiency losses due to intercalation. An ideal carbon electrode for nitrogen reduction would behave similarly to one suited to lithium metal batteries, it should facilitate lithium plating.
