Controlling SEI Formation on SnSb-Porous Carbon Nanofibers for Improved Na Ion Storage
Abstract
Porous carbon nanofiber (CNF)-supported tin-antimony (SnSb) alloys is synthesized and applied as sodium ion battery anode. The chemistry and morphology of the solid electrolyte interphase (SEI) film and its correlation with the electrode performance are studied. The addition of fluoroethylene carbonate (FEC) in electrolyte significantly reduces electrolyte decomposition and creates a very thin and uniform SEI layer on the cycled electrode surface which could promote the kinetics of Na-ion migration/transportation, leading to excellent electrochemical performance.
