Printed layers for encapsulation and redistribution in solid state batteries, and methods of making and using the same

Abstract

A solid-state battery cell and a method of making the same are disclosed. The battery cell includes a substrate, a cathode on or over the substrate, a solid-state electrolyte on the cathode, an anode current collector (ACC) on the solid-state electrolyte, a conductive bump on the ACC, an insulator layer on the ACC and having a sidewall portion, and a conductive redistribution layer in ohmic contact with the conductive bump and on the insulator layer, including the sidewall portion. The insulator layer surrounds the conductive bump and exposes a surface of the conductive bump. The method includes printing the conductive bump on the ACC, printing the insulator layer on the ACC and a sidewall of the ACC, solid-state electrolyte, cathode and substrate, and forming the conductive redistribution layer on the exposed conductive bump and the insulator layer, including the sidewall portion.
