Abstract
The invention relates to a pasty material that can be used in electrochemical components comprising (A) 0-70 percent by weight of a matrix containing at least one organic polymer, its precursors or its prepolymers or consisting thereof; (B) 30-100 percent by weight of inorganic material that can be electrochemically activated and that is preferably nonsoluble in the matrix in the form of a solid substance and optionally a suspending agent for (B). The invention is characterized in that the electrochemically activatable material is at least partially a nanocrystalline powder, with the proviso that material (B) is not a material that can be used as electrode material in the absence of (A). Said material is suitable for producing self-supporting layers or layers placed on a substrate, from which or with which layered composites with electrochemical properties such as accumulators, batteries, condensers (supercaps), solar cells and electrochrome display elements can be produced. The invention also relates to a method for producing said materials, layers layered composites.
