FIELD : chemistry.SUBSTANCE : invention relates to a counter electrode and an electrochromic device and its manufacturing method and can be used in the manufacture of smart glass or translucent structures with electrically controlled light transmission variable. A process for preparing a counterelectrode comprises obtaining the active layer having a high capacity for intercalation of lithium ions of the composition containing in % by weight in terms of dry substance : material with a high intercalation capacity - from 70.0 to 99.8; . electroconductive additive - 0.1 to 10.0; binder - 0.1 to 10.0; stabilizer - from 0.0 to 10.0, and the solvent - the rest. The ingredients of the composition are mixed and then applied by available printing methods on the substrate surface with a transparent electrically conductive material so that the surface area ratio, is free from the opaque material, is 92÷97%. Lithium cobaltate LiCoOand/or lithium ferrophosphate LiFePOand/or lithium manganate LiMnOare used as materials with high lithium intercalation capacity.EFFECT : invention provides improvement of electrochemical stability of the counter electrode, as well as increase in the number of working dye-bleaching cycles in the electrochromic device, that is the technical result of the invention.8 cl, 6 dwg, 4 ex |
