Single-Atom Ru Implanted on Co₃ O₄ Nanosheets as Efficient Dual-Catalyst for Li-CO₂ Batteries.

ABSTRACT: Li-CO₂ battery has attracted extensive attention and research due to its super high theoretical energy density and its ability to fix greenhouse gas CO₂ . However, the slow reaction kinetics during discharge/charge seriously limits its development. Hence, a simple cation exchange strategy is developed to introduce Ru atoms onto a Co₃ O₄ nanosheet array grown on carbon cloth (SA Ru-Co₃ O₄ /CC) to prepare a single atom site catalyst (SASC) and successfully used in Li-CO₂ battery. Li-CO₂ batteries based on SA Ru-Co₃ O₄ /CC cathode exhibit enhanced electrochemical performances including low overpotential, ultra high capacity, and long cycle life.
