Definitions

  • Solid or polymer electrolytes have a much lower conductivity than the electrolyte solutions used. They are therefore not suitable for the production of high-performance batteries.
  • Non-metals such as plastics, glass, carbon fiber and the like, provided that they have through openings and are flexible.
  • the substrate can be made from a 3
  • Examples are magnesium oxide, calcium oxide, strontium oxide, barium oxide, scandium oxide, yttrium oxide, titanium oxide, zirconium oxide, aluminum oxide, silicon oxide, tin oxide, cerium oxide, europium oxide, mixtures of these oxides or mixed oxides of the cations mentioned.
  • Examples of ternary oxides are: non-conductive spinels, non-conductive pyrochlores, non-conductive olivines. In contrast, electrically conductive ceramics such as (doped) semiconductor ceramics are unsuitable.
  • the electrical separator according to the invention is suitable for all arrangements in which electrodes have to be electrically insulated from one another.
  • electrodes have to be electrically insulated from one another.
  • they can also be used e.g. done in capacitors.
  • the separators are sintered in an inert gas atmosphere at 1000 to 1100 ° C for at least 15 minutes in an inert gas furnace.
  • Figures 1 and 2 show a separator according to the invention according to the example in cross section (enlargements: Figure 1: 130: 1, Figure 2: 648: 1). It can clearly be seen that the substrate is completely covered with ceramic, so that dendrites can no longer grow through. The mere presence of the open pores of the coating enables the unhindered passage of ions.

Abstract

L'invention concerne un séparateur électrique comprenant un substrat plat, flexible, comportant une pluralité d'ouvertures et un revêtement. L'invention est caractérisée en ce que le matériau du substrat est sélectionné parmi des métaux, alliages, matières plastiques, verre et fibres de carbone ou une combinaison de ces matériaux, et en ce que le revêtement est constitué d'un revêtement céramique poreux, s'étendant de façon continue sur toute la surface du substrat.
