Reduction of dinitrogen to ammonium through a magnesium-based electrochemical process at close-to-ambient temperature Energy Environ. Sci. (IF 32.5) Pub Date : 2024-05-23 Melinda Krebsz, Rebecca Hodgetts, Sam Johnston, Cuong K. Nguyen, Yvonne Hora, Doug R. MacFarlane, Alexandr N Simonov
The Li-mediated nitrogen reduction enables practical synthesis of ammonia, but its energy efficiency is limited by the Li0/+ redox potential. To improve on this, a mediator with a more positive potential, like Mg0/2+, is required. Herein, we demonstrate that electrodeposited Mg0 reacts with N2 at a close-to-ambient temperature, and the resulting material can be converted into NH4+. This two-step process

Optimal Facet Assembly of Multi-Transition Metals Layered Cathodes toward Superior Li-Ion Kinetics and Structural Stability Energy Environ. Sci. (IF 32.5) Pub Date : 2024-05-22 Feng Zou, Jae-Bum Kim, Jiliang Zhang, Gi-Hyeok Lee, Lulu Lyu, Junhyeok Choi, Timo Kankaanpää, Yong Min Lee, Yong-Mook Kang
The surface stability of layered cathode materials is a critical determinant of their chemo-mechanical reversibility during intercalation/deintercalation. This is possibly because of the migration of transition metals (TMs) into the Li layer followed by O redox, which decreases the O vacancy formation energy and thereby destabilizes the anionic framework. Hence, elucidating an optimal assembly of surface
