RuO2−x decorated CoSnO3 nanoboxes as a high performance cathode catalyst for Li–CO2 batteries
2020
Rechargeable Li–CO2 batteries contribute towards lessening fossil fuel depletion and alleviating the “greenhouse effect”. However, more efforts must be made to figure out the critical problems of a high overpotential and poor cycling stability associated with this type of battery. Here, CoSnO3/RuO2−x nanocomposites were employed as an efficient air cathode for Li–CO2 batteries, which can lower the overpotential and improve their long-term cycling performance (around 145 cycles) remarkably.
