Single‐Atom Cadmium‐N₄ Sites for Rechargeable Li–CO₂ Batteries with High Capacity and Ultra‐Long Lifetime (Adv. Funct. Mater. 25/2023)

Single-Atom Catalysts In article number 2213841, Zhenyu Sun, Yousung Jung, Xinyi Tan, and co-workers report, that single-atom cadmium with a Cd-N4 coordination structure enables rapid kinetics of both the discharge and recharge process when employed as a cathode catalyst, and thus facilitates exceptional rate performance in a Li-CO2 battery, even up to 10 A g−1, and remains stable at a high current density (100 A g−1).
