Post Nitrogen Electrocatalysis Era From Li–N2Batteries to Zn–N2Batteries

Abstract

AbstractMetal–N2batteries attract considerable research attention due to the dual‐functional characteristics applied in energy storage and conversion, as well as electrochemical artificial NH3yield. Nonetheless, it has been found that not all kinds of metal–N2batteries are suitable for combining the above two applications. Herein, recent advances in metal–N2batteries are summarized. First, the electrochemical reaction mechanisms for all types of metal–N2batteries, including organic Li/Na/Al–N2batteries and aqueous Zn/Al–N2batteries are discussed, and then, a critical assessment of current challenges and future applications is provided. Considering the different electrochemical reaction mechanism in the metal–N2batteries, the electrocatalytic performance for the reported catalyst cathodes is summarized and compared. Then, a multi‐dimensional feasibility and strategy analysis for the developments of rechargeable aqueous Zn–N2batteries is provided, including the three dimensions of cathode catalyst, electrolyte, and metal anodes. Last, specific suggestions and ideas for the further developments of the rechargeable aqueous Zn–N2batteries are put forward, with the hope of inspiring the further developments for the green, sustainable, and high‐energy‐density metal–N2systems in the future.
