The invention relates to an essentially flat electrode of an electrochemical system, such as a battery or a capacitor. Said electrode is comprised of at least one conductive (3) and of a storage layer (4), which is connected to said conductive layer, has a lattice structure, is comprised of woven or knit plastic threads (5) that are rendered conductive, and in which electro-active material is embedded. The aim of the invention is to improve the volumetric and gravimetric energy density with an adequate mechanical stability and simplified production. To this end, the local lattice structure of the storage layer (4) is matched to the size and electrical conductivity of the particles (1) of the embedded electro-active material and is matched to the current density, which exists each time during the operation of the system, in such a manner that in the case of poor conductivity of the particles (1) and/or of high local current density, essentially each individual particle (1) is in direct contact with the lattice threads (5), whereas in the case of good conductivity of the particles and/or of low local current density, particles (1) that are not themselves in direct contact with the lattice threads (5) are also located in a lattice pocket (6). |
