Ammonia is a vital chemical that is primarily used to produce fertilizer for agriculture, but also has uses in the chemical industry as a commodity chemical. Globally, more than 180 million metric tons of ammonia are produced annually by the Haber-Bosch process which is responsible for around 1 % of global carbon dioxide emission and requires large, centralized facilities to be operated continuously. Developing an alternative process to produce ammonia with less environmental impact and in localizable devices would enable on-site and on-demand production that can be coupled to the ever-growing renewable energy sector. Alkali-metal mediated electrochemical processes, predominantly the lithium mediated system has proven to be the best candidate for activating dinitrogen (N2) since its revival in 2019. Initially developed by Tsuneto et al. in the 1990's, the system relies upon in-situ electrodeposition of lithium metal from a lithium-based organic electrolyte, usually onto a metal working electrode. In conjunction with lithium metal, a solid electrolyte interphase forms which moderates the access of reagents to enable selective N2 reduction. Vast improvements in the Faradaic efficiencies of lithium mediated N2 reduction have resulted primarily from research focused on optimising the electrolyte or employing more industrially relevant cells such as a flow cell with gas diffusion electrodes. There have been a limited number of studies focused on the cathode material, most employ metal electrodes such as molybdenum or stainless steel. These electrodes exhibit low current density and electrochemical performance in terms of yield rate (nmol s -1 cm -2 geo) towards ammonia due to their low surface area. In the state-of-the-art flow cell, the cathode is commonly stainless steel mesh which is also limited by its low surface area. A recent study by Li et al. achieved 60 mA cm -2 geo in a flow cell by employing a high surface area gas diffusion electrode which produced ammonia with a Faradaic efficiency of 67 %. The synthesis of such cathode materials, however, requires deposition of high surface area copper on to the stainless steel substrate. Copper is known to be highly susceptible to corrosion in an ammonia rich environment, which may cause issues at high ammonia production rates. Carbon electrodes, both commercial and homemade, are commonplace in many electrochemical processes such as aqueous electrocatalysis and battery technologies. Carbon electrodes exhibit many favourable properties namely conductivity, high surface area, tunability and porosity. Several battery technologies employ carbon electrodes, most commonly lithium-ion batteries which store energy via intercalation of lithium ions into graphitic carbons. However, carbon has not been successfully employed in a flow cell for lithium mediated ammonia synthesis. Carbon's ability to intercalate lithium can be likened to metals alloying with lithium. The alloying of lithium with a metal is a descriptor established by Tsuneto et al. to screen electrode materials, who suggested that metals which alloy with lithium (aluminium and lead) would prevent lithium from activating N2. Translating this to carbon materials, the intercalation of lithium should prevent the reduction of N2 and production ammonia. In this assessment, the authors did not consider that the alloying energy is not constant with varying degree of lithiation.
