1. A material in sheet or web form, the material comprising: a support medium made of at least one construction material and having a three-dimensional total support volume having an x-dimension representing a length, a y-dimension representing a width, and a z-dimension representing a thickness≤100 μm; the support medium is a matrix of support elements including a plurality of linear support elements and a plurality of node-shaped support elements which form material components of the support medium and penetrate the total support volume; each of the plurality of linear support elements having three spatial dimensions including: a first dimension, a second dimension, and a third dimension; each of the second and the third dimensions being smaller than the first dimension; with a ratio of the first dimension to each of the second and the third dimensions being at least 50:1 and a ratio of the second and the third dimensions to one another being not less than 1:5 and not greater than 5:1; the total support volume being smaller in the z-dimension in comparison to that in the x- and the y-dimensions with the total support volume having interconnected cavities defined by the support elements neighboring one another; wherein the plurality of linear support elements have at least in sections distances from one another which are greater than 5:1 in relation to the larger of the second and the third dimensions; wherein the plurality of linear support elements and the plurality of node-shaped support elements are sheathed with a first functional material fulfilling a first function, and wherein a portion of the total support volume formed by the interconnected cavities is filled with at least one second functional material, which fulfills a second function that differs from the first function; wherein the support medium is a glass-fiber fabric tape, a carbon-fiber fabric tape, a mineral-wool-fiber fabric tape, a polymer-fiber fabric tape or a wire fabric tape; wherein the first functional material is a metal; and wherein the at least one second functional material is one of: (i) a substance mixture of lithium/nickel oxide, lithium/manganese oxide, lithium/cobalt oxide, or lithium/iron phosphate; or (ii) graphite.
