Mo₂C/CNT: An Efficient Catalyst for Rechargeable Li–CO₂ Batteries

The rechargeable Li–CO 2 battery is a novel and promising energy storage system with the capability of CO 2 capture due to the reversible reaction between lithium ions and carbon dioxide. Carbon materials as the cathode, however, limit both the cycling performance and the energy efficiency of the rechargeable Li–CO 2 battery, due to the insulating Li 2 CO 3 formed in the discharge process, which is difficult to decompose in the charge process....
