Regulation of the cathode inner Helmholtz plane in dilute ether electrolytes using an electric-field-responsive solvent for high-voltage lithium metal batteries

Herein, we demonstrate that the battery intrinsic electric field drives the specific adsorption of a weakly solvated co-solvent, DTS, to replace conventional DME in the IHP, enabling the desirable CEI chemistry on the 4.6 V LiCoO 2 cathode.
