Abstract

The addition of [EMIM]NO₃ effectively inhibited aluminium current collector corrosion in a LiTFSI-based electrolyte since both [EMIM]⁺ and NO₃^- could exclude TFSI^- from directly contacting the surface of the aluminium current collector as a result of competitive adsorptions. This work offers a novel technical solution to address the corrosion issue and may promote the wide application of sulfonimide salts.
