Abstract

Read online

Na metal batteries offer compelling merits; however, the safety issue remains to be overcome. Here, the authors report an ionic liquid electrolyte based on NaCl-buffered AlCl3/[EMIm]Cl with two additives including EtAlCl2 and [EMIm]FSI which serve to stabilize SEI for reversible Na plating/stripping.
