To make the Li‐CO2 batteries usable under ambient conditions, it is critical to develop highly efficient catalysts for the CO2 reduction and evolution reactions and investigate the electrochemical behavior of Li‐CO2 batteries. A lithium-CO2 battery with a holey graphene catalyst exhibited high rechargeability and superior long-term cycling stability over 200 cycles at ambient temperature. The researchers also found that the lithium metal was stable in its liquid state for up to 500 cycles.
