Multiscale Defective Interfaces for Realizing Na-CO₂ Batteries With Ultralong Lifespan.

ABSTRACT: Despite their favorable high energy density and potential for CO₂ recycling, Na-CO₂ batteries have been held back by limitations in cycling capability, stemming from the sluggish CO₂ reduction/evolution reaction (CO₂RR/CO₂ER) kinetics at CO₂ cathode and unmanageable deposition/stripping of metallic Na at the anode upon cycling. Herein, a "two-in-one" electrode with multiscale defective FeCu interfaces (CP@FeCu) is presented, which is capable of improving the CO₂RR/CO₂ER kinetics of CO₂-breathing cathode, while modulating sodium deposition behavior. Experimental and theoretical investigations reveal multiscale defective FeCu interfaces are responsible for the enhancement of sodiophilicity and
