Abstract
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.
