Abstract
Provided herein are battery cells comprising artificial solid-electrolyte interphase (SEI) layers used as protective coatings on electrodes. The SEI layers are produced by liquid-phase deposition (LDP). The battery cell may comprise an anode, a cathode, an electrolyte disposed between the anode and the cathode, a polymer separator disposed between the anode and the cathode, and a casing containing the anode, the cathode, the electrolyte, and the polymer separator, wherein at least one or the anode or cathode comprises an SEI layer produced by an LDP method.

A battery cell, comprising:
- an anode;
- a cathode;
- an electrolyte disposed between the anode and the cathode;
- a polymer separator disposed between the anode and the cathode;
- and
- a casing containing the anode, the cathode, the electrolyte, and the polymer separator, wherein the casing provides electrical contact to the anode and the cathode,
- wherein at least one of the anode or cathode comprises an artificial solid-electrolyte interphase (SEI) layer;
- and
- wherein the artificial SEI layer is substantially devoid of particle-to-particle internal resistance between the electrode constituent particles.
