Introducing competitive adsorption species in sulfonimide salt-based electrolytes for inhibiting aluminium corrosion†
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.
