Abrégé

A method of joining a substrate for a bipolar electrode of a bipolar battery to a frame for supporting the bipolar electrode for use in the bipolar battery includes the implanting of a thermoplastic material in the substrate. The substrate and the frame are then vibration welded together at a frequency in the range of 50 Hz to 1 kHz to melt the thermoplastic material. The melted thermoplastic material forms a continuous or substantially continuous loop around the substrate to join the substrate and the frame together. A bipolar battery comprising a substrate and a frame joined together by the method, and a substrate for a bipolar electrode for use in the method are also described.

A method of manufacturing a composite material, the method comprising: (i) providing a ceramic powder comprising ceramic agglomerates, the agglomerates having an intra - agglomerate void volume space; (ii) providing a polymer; (iii) mixing the polymer with the ceramic powder to form a mixture comprising the agglomerates at least partially impregnated with the polymer, wherein the volume of polymer in the mixture is at least 80% of the total intra- agglomerate void volume space, but less than 130% of the total intra -agglomerate void volume space; (iv) optionally shaping the mixture to form a preform; (v) and treating the mixture to provide ceramic agglomerates which are at least partially impregnated with solid polymer.
