1. 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 a stacked plurality of artificial solid-electrolyte interphase (SEI) monolayers;
wherein the plurality of artificial SEI monolayers are substantially devoid of particle-to-particle internal resistance between electrode constituent particles; and
wherein the plurality of artificial SEI monolayers are individually comprised of one or more polymeric materials.
