    摘要: A thin, flexible, porous ceramic composite (PCC) film useful as a separator for a molten-salt thermal battery comprises 50% to 95% by weight of electrically non-conductive ceramic fibers comprising a coating of magnesium oxide on the surface of the fibers in an amount in the range of 5% to 50% by weight. The ceramic fibers comprise Al2O3, AlSiO2, BN, AlN, or a mixture of two or more of the foregoing; and the magnesium oxide coating interconnects the ceramic fibers providing a porous network of magnesium oxide-coated fibers having a porosity of not less than 50% by volume. The pores of the film optionally can include a solid electrolyte salt. A laminated electrode/PCC film combination is also provided, as well as a thermal battery cell comprising the PCC film as a separator.
