A robust and ultra-stable sodium infiltrated Fe 2O 3 coated carbon textile (SFCT) anode has been designed. This SFCT anode overcomes the disadvantage of Na electrodes, which is not easily processable, and exhibits more flat voltage profiles, lower stripping/plating overpotential, and better cycling stability in an additive-free carbonate-based electrolyte compared with bare Na electrodes.
This study demonstrates a robust and ultra-stable sodium infiltrated Fe 2O 3 coated carbon textile (SFCT) anode with excellent machinability. The obtained SFCT anode overcomes the disadvantage of Na electrodes, which is not easily processable, and exhibits more flat voltage profiles, lower stripping/plating overpotential, and better cycling stability in an additive-free carbonate-based electrolyte compared with bare Na electrodes.
