Thermal insulation, especially for high-temperature batteries, wherein the thermal insulation has at least one hermetically sealed cavity which contains insulating material, characterized by the feature that the cavity is evacuated and is completely filled with at least one very fine insulating material in powder form in such manner that at least one first region of the cavity can be loaded with full pressure over the area and at least one second region of the cavity has very low thermal conductivity, and that these two regions are arranged immediately adjacent to each other.

Thermal insulation comprising at least one hermetically sealed cavity bounded by walls and without rigid bracing members between walls, filled with at least one insulating material in powder form said cavity having at least one first region in which the insulating material therein is more compact to resist inward and outward bending and pressures of an against the boundary walls, and having at least one second region in which the insulating material is less compact than the insulating material of the first region to impart low thermal conductivity to the second region, said first and second regions of the cavity are filled with very fine ceramic powder which is doped with microfibers, with the ceramic powder filled into the first region having a density of d0.5 g/cm3 and the ceramic powder in the second region having a density of d0.35 g/cm3 and said first and second regions being arranged immediately adjacent to each other.
