| 摘要 |
The present invention relates to a composite material, comprising or consisting of a coating material having particles, and a base material, wherein the surface of the base material contains depressions, which lead to a reduced base material thickness at the location thereof, wherein the depressions are deviations from a smooth, even surface of the base material, characterised in that the geometric dimensions and/or forms of the particles and the depressions are similar or the same, such that one or more particles fit geometrically in the individual depressions, either in whole or in part, or have penetrated through the application of force and/or energy so adherently that said adhesion is based at least partially on mechanical forces between particles and base material. The invention further relates to electro-chemical systems, batteries, fuel cells, electrolysis cells or double layer capacitors, which contain said composite material in the form of electrodes, and to a method for producing said composite material. |
