ELEKTRODE, IHRE VERWENDUNG UND ELEKTROCHEMISCHE ZELLE

Die Erfindung betrifft eine Elektrode für eine elektrochemische Zelle, welche ein Stück eines aus dotiertem Titandioxid gezüchteten Einkristalles ist oder eine Vielzahl von aus dotiertem Titandioxid gezüchteten Einkristallen (2) enthält. The electrode has monocrystals (2) grown from doped titanium dioxide. The electrode is a crystal plate cut from the grown monocrystals, and thickness of the crystal plate is between 0.5 mm and 10 mm. The electrode is embedded as a single layer in a plastic substrate layer (1) made of non-conductive material, where the monocrystals are exposed on sides of the substrate layer. The monocrystals have particle size between 100 and 5 micro meters, where the particle size is adapted to thickness of the substrate layer. The titanium dioxide is doped with lithium, niobium, aluminum, phosphorous, gallium, boron, arsenic, indium, germanium, iridium, ruthenium, rhodium, antimony, nitrogen, manganese, iron, cobalt, nickel, chromium or yttrium and oxide or fluoride of an element. The substrate layer consists of teflon(RTM: PTFE), polyvinylidene fluoride (PVDF), perfluoroalkoxy alkane (PFA), fluorinated ethylene propylene (FEP), ethylene tetrafluoroethylene (ETFE), polyetheretherketone (PEEK)(RTM: colorless organic polymer thermoplastic), polyphenylene sulfide (PPS), polyethylene (PE), polypropylene (PP) and PVC. An INDEPENDENT CALIM is also included for an electro chemical cell.
