Abstract
An embodiment is directed to a solid state electrolyte-comprising Li or Li-ion battery cell, comprising an anode electrode, a cathode electrode with an areal capacity loading that exceeds around 3.5 mAh/cm2, an ionically conductive separator layer that electrically separates the anode and cathode electrodes, and one or more solid electrolytes ionically coupling the anode and the cathode, wherein at least one of the one or more solid electrolytes or at least one solid electrolyte precursor of the one or more solid electrolytes is infiltrated into the solid state Li or Li-ion battery cell as a liquid.
