Graphene was introduced into Li–N 2 batteries to investigate the cycling stability, as described by Z. Zhang, Z. Zhou, and co‐workers in their Research Article on page 17782 ff. The low efficiency and irreversibility of Li‐N 2 batteries are due to the instability and hygroscopicity of the discharge product Li 3 N. Moreover, modification by Li 3 N and LiOH generated in situ reduces the loss and volume change of Li anodes during stripping and plating, thereby promoting the rechargeability of Li‐N 2 batteries.
