Abstract :
Fluoroethylene carbonate is an efficient electrolyte additive to improve 
the reversibility of electrochemical sodium insertion for hard-carbon 
and NaNi1/2Mn1/2O2 electrodes in aprotic Na cells. The additive is also 
capable of the electrochemical deposition/dissolution of metallic Na 
with higher reversibility because of improved passivation and 
suppression of side reactions between Na metal and propylene 
carbonate solution containing Na salts.
