A robust 3D host for sodium metal anodes with excellent machinability and cycling stability

Abstract

This study demonstrates a robust and ultra-stable sodium infiltrated Fe₂O₃ 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.
