Abstract
Electrochemical cells and methods for making electrochemical cells are provided. In one example, an electrochemical cell includes a positive electrode, a negative electrode, and a separator that is disposed between the positive and negative electrodes. The separator is electrically insulating and ionically conductive. An electrolyte is operatively disposed between the positive and negative electrodes and interfaces with the separator to conduct ions between the positive and negative electrodes. A porous ceramic powder impregnated with an intermediate oxidation state alkali metal compound is coupled to one of the separator and the positive electrode.
