Abstract
A cathode composite layer for an ASSB cell comprises cathode active material, a solid electrolyte, and conductive pathways. Each conductive pathway comprises a cylindrical carbon nanostructure having a first end and a second end with an exterior wall extending between the first end and the second end, and an insulating sheath covering the cylindrical carbon nanostructure except in an uncovered portion of the cylindrical carbon nanostructure, the uncovered portion being the first end and a first portion of the exterior wall directly adjacent the first end and the second end and a second portion of the exterior wall directly adjacent the second end.
