Abstract

In an embodiment, a metal-ion battery cell comprises an anode electrode, a cathode electrode, a separator, and electrolyte ionically coupling the anode electrode and the cathode electrode. The anode electrode is a high-capacity electrode (e.g., in the range of about 2 mAh/cm2 to about 10 mAh/cm2). The electrolyte includes a solvent composition, the solvent composition including low-melting point (LMP) solvent(s) in the range from about 10 vol. % to about 80 vol. % of the solvent composition as well as regular-melting point (RMP) solvent(s) in the range from about 20 vol. % to about 90 vol. % of the solvent composition.
