Abstract

An electroactive material for an electrochemical cell includes one or more oxygen storage material coatings or layers. The electroactive material may include a plurality of electroactive material particles disposed to form an electroactive material layer. In certain variations, at least a portion of the plurality of electroactive material particles may have a coating that includes an oxygen storage material. In other variations, an oxygen storage material layer may be disposed on one or more surfaces of the electroactive material layer. In still other variations, at least a portion of the plurality of electroactive material particles may have a coating that includes an oxygen storage material, and an oxygen storage material layer may be disposed on one or more surfaces of the electroactive material layer. The one or more oxygen storage material coatings or layers may help to improve the thermal stability of the electroactive materials.
