Abstract: The disclosure provides a solid-state battery including a cathode comprising a lithium-based conducting material having a porosity less than or equal to 6% and a surface roughness of equal to or less than 300 nm. The solid-state battery may also include an anode and a solid electrolyte between the cathode and the anode.
