While lithium hexafluorophosphate (LiPF\n                    <jats:sub>6<\/jats:sub>\n                    ) is widely used, its chemical instability (e.g., generating HF) undermines battery performance. Lithium imides such as lithium bis(trifluoromethanesulfonyl)imide (LiNTf\n                    <jats:sub>2<\/jats:sub>\n                    ) improve chemical stability but corrode aluminum current collectors above 3.7\u00a0V, motivating the development of non\u2010corrosive alternatives. Herein, we report a non\u2010corrosive methide\u2010based lithium salt, lithium bis(trifluoromethanesulfonyl)methide (LiCTf\n                    <jats:sub>2<\/jats:sub>\n                    ), in which the central nitrogen of LiNTf\n                    <jats:sub>2<\/jats:sub>\n                    is replaced by a methine (\u2500CH\u2500) moiety, modulating the electronic structure of the CTf\n                    <jats:sub>2<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    anion to promote the formation of low\u2010solubility Al\n                    <jats:sup>3+<\/jats:sup>\n                    complexes and thus suppress corrosion, while enhancing coordination with Li\n                    <jats:sup>+<\/jats:sup>\n                    to reinforce solvation structures and establish denser interphase.
