A method of preparing a ceramic matrix composite (CMC) component that includes a protective ceramic layer comprises adhering at least one flexible ceramic tape to a ceramic fiber preform, where the at least one flexible ceramic tape comprises ceramic particles dispersed in an organic binder phase. After the adhering, the at least one flexible ceramic tape is heated to a temperature sufficient to volatilize the organic binder phase, thereby forming a porous ceramic layer on at least a portion of the ceramic fiber preform. After the heating and volatilizing, the ceramic fiber preform and the porous ceramic layer are infiltrated with a molten material, thereby forming a CMC component including, on at least a portion thereof, a protective ceramic layer.

The invention discloses a packaging film for a battery. The packaging film for the battery comprises an electrolyte-resistant layer, a protective layer, and a high-rigidity material layer. The high-rigidity material layer is located between the electrolyte-resistant layer and the protective layer. The high-rigidity material layer comprises a substrate layer and at least one cermet film. The substrate layer has two surfaces facing the electrolyte-resistant layer and the protective layer respectively. The at least one cermet film is located on at least one of the two surfaces of the substrate layer.
