Abstract
Official abstract text for this publication.
Batteries such as Li-ion batteries are provided that comprise anode and cathode electrodes, an electrolyte ionically coupling the anode and the cathode, and a separator electrically separating the anode and the cathode. In some designs, the electrolyte may comprise, for example, a mixture of (i) a Li-ion salt with (ii) at least one other metal salt having a metal with a standard reduction potential below −2.3 V vs. Standard Hydrogen Electrode (SHE). In other designs, the electrolyte may be disposed in conjunction with an electrolyte solvent that comprises, for example, about 10 to about 100 wt. % ether. In still other designs, the battery may further comprise anode and cathode interfacial layers (e.g., solid electrolyte interphase (SEI)) disposed between the respective electrode and the electrolyte and having different types of fragments of electrolyte solvent molecules as compared to each other.
