Significance Li-CO2batteries not only act as promising carbon-neutral technology to provide a method of CO2fixation for serious global warming, but also offer opportunity for applications such as Mars exploration or submarine operations with CO2-rich environments. We design an efficient bifunctional activity in 2D materials with a large number of dual active centers, realizing highly reversible Li-CO2batteries with an ultra-small voltage gap of 0.68 V and an ultra-high energy efficiency of 81.2%, which is superior to those of previous catalysts under similar conditions. This work not only paves an avenue to understand and realize rationally manipulated electronic contact of 2D materials with specified crystal facets, but also offers guidance for designing high-performance catalysts for Li-CO2batteries.
