Abstract
A solid-state cathode for a solid-state electrochemical cell includes an electrochemically active cathode material and one or more elemental dopant residing in grain boundaries of the electrochemically active cathode material. The grain boundaries contain at least 0.2 wt % of the one or more elemental dopant and the one or more elemental dopant is less than 10 wt % of the solid-state cathode. The solid-state cathode does not have liquid, gel and polymer materials.
