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.

Abstract: A battery includes an enclosure, a battery management unit (BMU), a conductive trace including conductive particles disposed on a surface of the enclosure and electrically coupled with the BMU to form a closed-loop electrical path. The BMU is configured to detect a resistance in the closed-loop electrical path caused by a percolation of the conductive particles, and determine a swollen condition of the battery based on the resistance.
